JMLS Disappearing Glitch

Just wasted a ton of time and energy because whenever I go for the JMLS Ult during conquest, he just disappears. Like, it goes into the animation, but no fancy Master Luke Skywalker, just blank space. Since he can't go through his animations, his turns are extra long. It's meant that every time I get close to finishing my Great Mother Sector 2 feat farming, the game is effectively a loss because I can't finish them. Similarly (and, I think, related), when I defeat enemy toons, the game counts them as defeated (they're removed from turn order) but they remain standing for some reason.

Please let me know if there's anything that will fix this -- I'm tired of wasting crystals and conquest energy trying to reach this milestone if it's just not gonna work.
