Minions stopped summoing

The Local Bone 117 Minion Union appears to be in strike, because mine have refused to summon all of a sudden. I finished Ogham Village and for a couple of T5 gems, so I added bone storm and raise zombie, also taking the opportunity to swap out wand and septor for sector and shield. Suddenly, I have Red exclamation point next to my skeletal archers, with the warning that I don't have the required spirit. I still have 17 spirit in reserve, so this strikes weird. I tried reducing the count to one, with no effect. I tried removing all new skills and replacing all original equipment, all to no effect. My minions just don't work. I can't tell if it's bugged or if I did something inadvertently. Thoughts?

Thank you.

I had something similar happen, I set my shield in weapon set II to be used for shield rush. I used it once, and then my character would NEVER use my slot I weapons again, all summons went away, and it messed up my spirit.

Yes, I've checked spirit allocation per weapon set.

The only solution I found was to take off all my weapons, then put 1 set back on (Set II now) and use that. Set I is now bugged and doesn't work. But changing the weapons to Set II magically re-summons my skeletons.
