So, there’s a bug with the new control effect duration changing code where these effects never wear off if the demon is in your stash
That’s pretty bad, and I’ll be rolling out a fix ASAP.
However, it’s somewhat of an illusion: if you summon the critter, the effect should wear off before it takes it first turn still. Just means you can’t remove it while resting if they’re stashed, which is annoying and bad.
Anyway, fix will be coming soon. Sorry about that. Even I don’t think of everything, sometimes.
