Witch/ Minion count bug

Playing as a witch with a minion scepter, I have raging fire skulls on and one minion fire thrower with 130 spirit. everything was going fine and then they just went away. the game gave me a error saying i didn't have enough spirit. It said, i only had 30, which was not the case. I have 6 remaining with my minion counts current set up. this happened once before and the issue resolved it's self. Now it is doing it again, and im not sure what to do. I've unequipped my gems, restarted, verified game cache, zeroed my minion counts and reset them. I'm at a loss :(

Thank you so much for everything you do and your time resolving this
