Yeah, these crates became a thing after they changed how cabinets are populated. IIRC to make difficulty option affect those? I'm a neat freak so they bother me a lot on otherwise very clean subs, even though cleaning them up is easy. Especially with bots.

No worries about the messages. I have done a quick update to add tags to the cabinets, except the weapons one. Unfortunately it spawns way too many weapons if I do that (the crate only gives a couple of items) - I've tried setting a random cabinet to secarmcab without autofill, but then it spawns the crate anyways (at least from what I can tell).

I faintly recall making most of my subs back when crates wouldn't spawn for missing supplies, so I only ever put tags if I wanted things to spawn with some randomness - and when the crates did spawn, I didn't pay much attention to those. :D
Maybe I'll make a pass on the other subs for these things at some point.

Sorry for the spam, this will probably be the last of it. Actually, now that I think about it, I recall there being a toggle that controls cabinets being auto filled with stuff. I think that affects all this the most. So I'm pretty sure that even if you had multiple cabinets with same default tags, only those tagged for fill would get stuff appropriate to the amount of cabinets with that toggle.

If there were multiple identical cabinets with same tags, then yes I think all of them would get populated with stuff automatically. However every sub has a starting minimum amount of supplies it gets and if there's no proper tags they get put in crates instead of proper cabinets. In case of this sub there's only one medical cabinet, so that wouldn't be an issue.

That stuff spawns either way. The difference is without tags it will spawn in crates.

If I'm not mistaken, the cabinets are set to automatically spawn equipment, so if I were to add those tags they would spawn additional stuff; not that it's a bad thing, mind you, but the sub wasn't meant to have things like weapons (aside from harpoons) available from the start.

Medical Supplies cabinet is missing medfabcab tag, which makes some of medical supplies spawn in crates. Also, there's no Secure Cabinet or Toxin Cabinet which cause similar "issue". maybe those could be added? Or appropriate tags could be added to existing cabinets?

Hey, thanks for the feedback! Bots cycling the airlock every now and again SHOULD be fixed. As for the oxygen refill, the suit locker cannot be wired to anything sadly. That said, even if the oxygen tank one can be hooked up to power, I'd rather not touch it - this might sound like a poor excuse perhaps, but I like to leave something to do either with oxygen refill duty or some quick manual wiring. If you'd like to do that yourself, the rightmost lower junction box in the battery array room has 2 unused wire slots that can be used for that.

Saw your post on Reddit and decided to scope out some of the submarines, starting with this one. :) Just a little feedback:

1: In the campaign the bots kept cycling the airlock so it was full, making the poor vertical movement even worse, if not outright stalling the sub. Would happen multiple times in every zone.
2: If the diving suit locker/oxygen tank locker next to it could be hooked up to power so they could slowly refill, that would be a nice QOL improvement, especially when playing with bots who will leave partially filled suits and tanks everywhere.
3: With the batteries at 100% charge rate, every time I'd cap out on power at an outpost, the outpost would immediately be overvolted and junction boxes would explode. Would advise to anyone checking out this sub maybe lower your battery recharge rate to 50% if not lower. I do enjoy battery powered subs as opposed to reactor based though.

3 is more an observation, doesn't really need a fix. 16 battery just = big load.
