After updating from 1.16.5 to 1.17 using the same world everytime my gf leaves it crashes the server. Nothing happens when i leave though (merling). Unsure whether it has to do with the third-party origin she's using (vampire from Haema mod) or something else.

If you need any additional info i'll try my best to provide you with it

I don't know what could be causing this. The crash seems to come from the getSpawn method, but I'm unsure why that would be called when a player leaves the server. Do you have a list of other mods you have installed? Maybe there is some mod that does something with your spawn on logout (e.g. teleport you to the spawn for logout? Idk...).
