Good Morning Radiant
I had an error in the latest build when closing down a window, the window was from a tradesman selling wooden goods and i was on the sell page, i was able to close down other windows fine and this one did close too but gave me the errors in the screenshots.
Notes: i already had the Citizens Window open and (although it’s likely a coincidence) 3 of my citizens achieved a new level at the exact same moment i clicked the close window button.
hope this helps
ps. the game is running really well everywhere else although i did get stuck on the generating world new game screen after clicking to re-roll the map generation a few times.
