I saw a few people getting mad about their characters dying due to bugs, boats dissapearing and such; but jorb said it was too problematic to resurrect them.
My (quick) suggestion is to just pump the character with a bunch of xp close to what they originally started with if you can figure out they actually died to bugs and arent lying about it; for example right after a big server crash or something.
The alternative to this is just having a bug specific curiosity: something thematic like a miniature anomaly or some chaotic magic item (a joke about game insability) which is bascially just a untradeable curiosity, drop a bunch in their inventory equivalent to the XP owed. Give it 1 weight and a quick study time so you can spend a couple minutes regaining your XP.
It's not a huge deal to me, but i think it would solve people getting upset about character deaths due to bugs.
EDIT: I'm holding out on playing hafen for a while due to studying, but if the death mechanics work the same maybe have some ultra food and stuff too for characters.
