I like the Pelanoir shuttle, but I have noticed that the airlock tends malfunction from the second respawn onwards. It launches with both doors closed, so you can't ever get back inside the airlock, and you're trapped unless you manage to perform either a proper docking, or crash the shuttle. Is it possible to add a button that resets the airlock to a state of the outer door being closed and the inner door being open?
As the Kullervo (especially it's shuttles) showed some trouble since update 8 (due to relay problems), a member of the Barotrauma Server community decided to take a look at your sub and apply some fixes.
Changes are (by Syrox):
shuttle relays no longer break
Shuttle charging now works and is fed by batteries
reactor settings changed to support charging
Doubled base welders and masks from 5 -> 10
Added more diving suits
Added Ethro, Fibro, Corri, and Aux to medical cabinets
