The new UF is sluggish and this keeps popping up. 
I’m trying to pinpoint where the problem is, I hope you don’t mind me asking some questions. Does the error happen immediately when opening the game? Or does it happen at a specific point?. Are you loading from a save file? If so was it made from a version of the game before chapter 2? (Also, as an aside: I’m still doing a lot of tests with the Android version of the game, and the new chapter has a lot of elements not designed for mobile devices. I’m still redoing that right now and will have an mobile-focused patch soon.)
