I'm making a pixel art with elements, and this is the problem: it's horrible the fact fire view exists in thumbnails, because it simply ruins the thumbnail.
Also, thumbnails don't update when you upgrade the save.
Copy of my other post: @ThunderSt Maybe ask Simon about the thumbnail problem, he might have broke something when resetting all the thumbnails. (How long has it been exactly?, they do take a little while to update) Also, the second one has always been happening. Saving and loading render options with saves would fix it, my mod does it, but the official version doesn't.
