0.10.8 (and previous) Edit: 0.10.9
I was hoping the new compiler would help but there’s still a few seconds of lag for me when closing treasure windows when there are lots of pages. 1-3 pages seems to be no problem, but the more pages the more lag. High CJ modifiers and leveled treasure talismans increase the issue as you get more pages of loot. Not sure if there is anything that can be done to optimize this part to reduce some of the lag.
