Skeleton Warriors absent

11/21 approx: 12:00 midnight While going through act 1 campaign playing as a level 9 witch with a rare scepter my skeleton warriors suddenly disappeared (zero spirit) and would not respawn no matter what was equipped or skills selected. Spirit remained at zero no matter what I removed or equipped. I tried going to several different areas to confirm. After discussing in global chat and troubleshooting with the community, I logged out and upon logging back in my skeletons spawned normally without having made any changes to skills or gear. I hope this is helpful, thank you.
