Some ships are spamming these 2 errors in my game:

My log is getting swarmed by these, and because of that my game slows to a crawl. Started getting those errors yesterday. I have hospitality (and a lot of other mods) installed. Destroying the ships with the dev tool fixes the issue. Please fix this mod, the game is impossible to play with these errors.
