I noticed an issue today that my spirit workers are unable to mine gold from my gold shrines. They will mine and the gold will build up in their inventory, but when it hits 1000G the gold simply vanishes rather than dropping on the ground. They then start over again.
I did not have this issue with regular workers who where able to drop the gold as intended.
I was also playing on a custom sandbox map made in the map editor. (incase that matters)
