When storing Enderman mob heads within a Storage Drawer they are visible through chests / blocks. This is specifically with Enderman heads, trying other mob heads (Creeper / Zombie / Skeleton) they do not do this. I guess the bug might be with p455w0rd's Things therefore?

Many thanks

If this only happens with the other mod present then sure.

But otherwise it's probably that the enderman heads set a funny render state and don't restore it, and I'm not watching to clean up after it. There have been similar problems with other mob heads and items in the past.
