I found a bad bug.
Port was UZdoom version 1.14.3
I had loaded the mod with "Improvisation" with this one being loaded last.
Normal Doom 2 maps.
It seemed to work fine, I got them on either monster kill or secret findings, threw them and they spat out items without a problem.
Then I decided to be cheeky and threw one at an enemy thinking it may hurt one, instead it froze the game haha.
To clarify, it froze once the dice hit an actual enemy, specifically a machinegunner from vanilla enemies.
