Now I have quite a lot of mods, so that is probably causing it, but when I look at recipes for things that come in dungeon chests, FPS goes down to like 1-2.

Using 0.1.0.10

I'm having the exact same issue as well. I also experience ctds if I try and click through or try to complete another action like taking a screenshot or backing out of that screen too quickly. It would be perfect if the loot screen could be trimmed down to show just the resource you're looking for.

I am pretty sure I have rectified this issue - I am currently testing and will post the new build asap

Can @Ikenowski and @BBoldt to have a go with build 13 - should fix this issue

That did the trick!

No lag at all with the new build.
Thanks!

Awesome - I'm gonna close the issue then - feel free to squawk if you run into anything new
