Max time compression and diving schedules regularly causing suffocation on VIIs

[Para]

So yeah, as per the topic. Had my boat on a diving schedule (surface at night, periscope in the day) with the snorkel activated. Switch to the highest TC (x54000 is it?), and suddenly air supply is at 0 submerged, with multiple crew down. Checked, and the diesel compressor is running...

Seems like the boat surface>compressor on>dive. But at the dive phase, probably because of the high TC, the compressed air tanks are not full yet, so compressors are not turned off. It also could be rough seas at that time, blocking the snorkel, so air supply gets expended very quickly.

A possible solution may be to add a compressor stop to the diving sequence regardless of the air tanks percentage.

In the meantime there seems to be no point using the diving schedules anymore on the VIIs, at least not with the snorkel up.

How are you diving with the compressor on again? That's highly unusual.

High TC causes bugs/unintended actions regardless... Was true for the Silent Hunter Series and still true with Uboat.

Avoid using greater than x1800 for extended travel, and no more than x140 when around land or enemies.

Using x54000 at all is just asking for trouble.

The diving schedule, plus the snorkel is up.

[DECAFBAD]

So during high TC the compressor can be on for more than 10 hours, is that the issue?

I think because it was the diesel compressor, so with the snorkel up, it continued running, even if diving. Which actually won't be a problem on calm seas. But on rough seas, with the snorkel blocked for an instant, all the air supply will be sucked by the compressor..

But yeah, as [XIII]Opsec says, all this won't be a problem if not using x54000.

[DECAFBAD]

Why is the compressor on in the first place? Who turned it on?

[Para]

I think it's the diving schedule. Not too sure, but it looks like turning on the compressor is part of the surfacing sequence.

In general you shouldn't use the highest time compression for anything but long distance transit on the surface, and only if you have your crew schedules set properly. It just causes too many issues that I'm guessing weren't solvable leading to the system the game uses of time compression blockades in certain situations.

[DECAFBAD]

I'm unable to reproduce this issue.

[Para]

I just reproduced it again.
1. In a VIIC/41 with snorkel extended
2. Dive schedule at "dive" from 0600 ~ 1900
3. Sail from La Rochelle to the Atlantic at speed "Forward 3"
4. Once out of port, set to dive schedule and put to max TC
5. Encounter rough seas and suffocate when submerged

And sorry, my mistake. Max TC is just x15000.

And with high time compression, discipline bonuses are not taken into account and it falls.

From what I noticed any commands you give only happen around the time when your captain says the voice line(or the command appears in the log), no matter the time compression.
It seems to me every action takes the same amount of real time and does not get multiplied by the time compression.

Easy to notice when ordering a hydrophone dive, cancel it early and then do another dive after the ship surfaced, all in quick succession at x1800 TC or higher.
If you don't wait a moment for the command to activate the compressors to actual be said/happen the compressors will never be turned on, even though half an hour or so passed in game time, while you were briefly surfaced.

I imagine it's the same thing for a dive schedule on high TC, you probably need to set the surfaced times between dives to be long enough for all commands to come through(which sucks hard). Lost my boat several times that way, not going to use that again.
