Maintain Position/Ballast Bug?

[shrekstyle]

Before the update the ballast would correctly work if you flood an airlock the ballast would keep the sub neutral if it could, with maintain position.

One of my subs has 2 airlocks that are different sizes and either one (not both at the same time) could be flooded and make the ballast go to around 5-10% full to keep neutral buoyancy, now when i flood the larger airlock the sub starts to sink quickly and the Ballast is about 25% full, with maintain position on. (it can just "only just" keep the sub neutral with the smaller airlock flooded)

If i go to manual control and make the sub move up it empties the ballast tank and makes the sub rise then i can fine tune it to make it neutral. but once i switch to maintain position it adds more to the ballast and makes it sink again.

i have checked the ballast numbers of the ballast hull rooms and they are still set in the nav-terminal correctly.

I have tested it in the editor with a test sub built just for this and it remains a problem where maintain position wont keep neutral buoyancy if it should be able to, but manual control can easily.

short version : the sub wont maintain position if the airlock is too big even if there is enuff ballast to allow it.

On further testing with maintain position and airlocks...
I noticed that interacting (just viewing) the nav-terminal or status monitor would cause the ballast level to change after the airlock was +64% flooded.

Sub stats
Total Hull ; 1,658,368
Ballast Hull ; 272,896 (Optimal buoyancy 0.4254)
Airlock Hull ; 89,600 (insufficient buoyancy capacity)

Helm set to maintain position.

Airlock flood level 0%-64%
normal ballast control 42%-21%, no change when viewing or not viewing the nav-terminal or status monitor.

Airlock flood level 72%
ballast room level 18% when viewing nav-terminal/status monitor (slowly maintains depth)
ballast room level 21% when not viewing nav-terminal/status monitor

Airlock flood level 85%
ballast room level 15% when viewing nav-terminal/status monitor (slowly maintains depth)
ballast room level 21% when not viewing nav-terminal/status monitor

Airlock flood level 89%
ballast room level 13% when viewing nav-terminal/status monitor (slowly maintains depth)
ballast room level 21% when not viewing nav-terminal/status monitor

Airlock flood level 95%
ballast room level 11% when viewing nav-terminal/status monitor (very slowly maintains depth)
ballast room level 21% when not viewing nav-terminal/status monitor

Airlock flood level 100%
ballast room level 10% when viewing nav-terminal/status monitor (cant maintain depth)
ballast room level 21% when not viewing nav-terminal/status monitor

Airlock flood level 100%
ballast room level 0% in manual helm controls ; fast acceleration to -8 y_velocity (up)

Do ships sink easier now or are we just ass?

So me and a buddy started a coop campaign for the first time after the Abyss and it seems like even the slightest bit of water will absolutely tank the sub with no chance of the pumps getting rid of it, even just the water that goes into the airlock while leaving the sub (yes we closed the door) would sink the ship to the floor. We have tried 2 different subs: the dugong and a workshop sub called the Sweetpea and both have the same problem although the workshop ship would sink almost immediately even though we frantically ran around repairing everything. So are we just trash or did this update change something?

Don’t think the update changed anything like that

♥♥♥♥. Was hoping we werent just ass at the game but oh well. We'll figure it out.

Do you have any gameplay mods installed? What you’re describing doesn’t sound normal or like a skill issue.

None besides the sweet pea which we have never had a problem with before but it does this with the dugong as well. Even just now the ship was fine and then as soon as we left the airlock and shut the door it started sinking. We were even already on the floor. Its getting pretty ridiculous at this point, playable but annoying. This has never happened to us before today as well.

There is a bug now with airlocks, the maintain position and ballast tanks dont work properly after the update.
Check my thread in the help and technical support forum for the test i did.

Glad im not the only one getting this.

I noticed this in the unstable branch with a workshop sub, I was hoping it would be fixed before going live. Opening the airlock for even a few seconds would cause the sub to sink like a rock.

Yup. Exactly whats happening to us except with both vanilla and workshop subs. Really hope they fix this as its a huge inconvenience to hope theres a rock to "park" the sub on every time you wanna leave your sub.

Yeah also good to know we're not the only ones experiencing this. Hope your post gains some traction and eventually gets seen by devs.

I noticed this too. Having the airlock full of water significantly affected the buoyancy, more than it should, and also caused issues maintaining position.

Me and friends also noticed this bug and it is really annoying. We used to play with a workshop sub (Pirahna) which had an airlock flooding system for thermal artifacts, and just this tiny bit of necessary water in the sub caused it to be stuck on the floor of the map.

We had to switch back to Humpback if we wanted to play and even then opening the airlock just sinks the sub.

I also noticed ballasts were behaving quite differently and its much harder to maneuver the sub. Hoping this will be patched soon

It is what custom submarine creators should patch. Tho, you may do in-game edits of your submarine and try to fix it yourself if you wanna

what i'm hoping to be patched is subs sinking when you only do so much as opening the airlock to get in/out. There definetly wasn't this problem before the abyss update and it messes up with both custom and default subs

The only way to fix it is to remove airlocks until the devs fix the bug.

Before the update the ballast system would work correctly and drain to maintain depth but now they dont once the airlock is above a certain weight and no one is on the nav-terminal manually controlling depth it wont drain the ballast tank to counter the extra weight.

On the test sub i built it could handle manual control and rise with the airlock fully flooded then switching it to maintain position causes the ballast to fill more than needed and the sub sinks.

I also seen the tanks change water level when viewing and not viewing the nav-terminal, with a flooded airlock and viewing the nav-terminal the ballast tanks would be at 11% and the sub would sink, then not viewing the nav-terminal the ballast tank would fill too 21% and sink the sub faster, then once viewing the nav terminal it would empty to 11% again.

On manual controls with the same sub and flooded airlock it could easily rise at a speed of -8.

The maintain position and its ballast controls are bugged, Devs need to fix it not sub creators.
