Thanks for the report! This will be fixed in 4.1.1. If you're curious, it only happens if a particular pirate is the last one you kill (the one with the cape just at the top of the stairs).

Hey,I got 2 updates today, First one was 200 mb, second was 1,5 GB. After updates though my last few saves say "missing DLC - LAXI / LAXI" when I try to load them. Obviously I can't load them. Probably something bad happened between updates.Help please, thanks

We're aware of this issue and we're hoping to have a fix out tomorrow. https://forums.obsidian.net/topic/107402-missing-dlc-suddenly/
