Movement Speed Slowdown Glitch (Unplayable)

[Leviticus Cornwall]

Hey guys,
I'm really enjoying this game as Engineer, but in about half of my games, at a certain point I will just start moving at close to zero movement speed. It might have something to do with the potions? I always use them. Ive seen some people say this is related to the APC, but Ive gotten it as early as the very first floor

this is really hard to find, if you can show me a recording at which moment it exactly happens I can likely find it but nobody could show me yet

In my experience, permanent slowdown has happened in co-op to the non-host player when they open an ammo box in a boss room. Once a noticable stutter happens, their speed is ~220 base. Does that sound like what happened? I've also heard of something happening with flinch staying permanent, but i haven't experienced that personally.

This just happened to me. I entered into the APC boss and my movement speed immediately dropped to 180. Hadn't fired a single bullet, did not have the LG-2 equipped. Wow, just to check, I did equip it and it dropped to 132.

it happened to me twice in about 300 hours. One time it happened right after a massive ♥♥♥♥♥♥♥♥♥♥♥ of explosions while I was playing as Breacher. I got the massive movespeed boost from all the explosions, then the game froze for a bit and when I regained control I was absurdly slow.

The other time there wasn't anything that prompted it, it felt like it happened out of nowhere with Engineer.

i think i know which enemy makes the movement glitch happen. i think the room clearing unit is the cus of the glitch and it happens randomly because sometimes it occurs and sometimes it doesn't but i'm almost sure the room clearing unit is the cus

Have the same bug. Speed went to 180.

[MaximmionVoss]

Have the same bug. Movement speed 191 on Tec 9 weapon.

+1 for this bug. Happens every now and then on the Armored transport

Same here, after fight with APC my Breacher moved like in mud.

It happens about half the time I fight APC. It is definitely tied to APC, more often again HG. I am not sure if it happen during fight or directly after it dies.

It mostly happens to me on the Armored transport with the Heavy Gunner. It also happened during a random stage (area 2) where I took damage when onslaught is on. I think the guy who mentioned the room clearing unit is maybe right?

+1 Keep having this issue on the APC boss while playing Heavy

I just had it happen after a firefight with Raider. It was a floor or two after the 1st boss and while I was moving to the next group of enemies I noticed my movespeed was reduced by over 140. After taking a teleporter I noticed the movespeed reduction was still there and that the firerate for my weapons, namely my nailgun was reduced by half as well, enough so that I couldn't even unload half a mag of the nailgun before overheating.
The only thing I can think of is that it's related to an enemy debuff that didn't wear off. I doubt it had anything to do with me doing the mystery boost since I dropped the weapon it gave me early on.
