yes, I have the same issues here. Even tho I dont use growables. I use extra assets, custommade. The thumbnails were there and suddenly they disappeared. Thats somehow very annoying :/

I just started using this mod and I'm getting the same issue. Grey boxes for almost every graphic :/

Same. Any fix to this?

Same. Can't even figure out how to use it and when I add something it's a grey box and I can't select it.
