Minecraft v1.15.2
Forge v31.2.36
Windowlogging v0.0.1
Block Carpentry v0.7.2

The Frame & Illusion Fences from Block Carpentry can be right-clicked with any block to take a new texture, but if it is windowlogged, the block will drop and then if the fence is broken, the block is dropped a second time, so basically infinite blocks.

I can't reproduce this anymore, in my testing the block gets windowloged and doesn't take on issusion properties
