I put the stack of amethyst shards on the ground in the spell stack, I use introspection and retrospection to make a spell list and I draw the symbol to make the cypher/trinket/artifact. The spell sound occurs, the stack clears and the particle effect happens, but both the hexcaster and the amethysts on the ground don't change a bit. I was using version 0.8.0

known issue, will be fixed with 0.8.1
