Minecraft v1.15.2
Forge v31.2.19
BasseBombeCraft v1.43-server

The Book of Copy & Paste seems to be finicky. Sometimes when right-clicking blocks it doesn't do anything, other times I can save the first marker, but the second won't save, and I cannot seem to paste it.

Looks like there is a server error occuring actually.
