Leveling up bug

SpartanGhost

Honestly how many more bugs do I need to report.

I can't even put iso into my champions now. I've tried resetting the game. Switched from WiFi to data and back again. I've cleared my cache. Etc etc.

Just another day in Marvels contest of Bugs

I had that once when I crashed got disconnected while levelling up. You have Tier 6 ISO in your inventory that is already "spent".
It went away after a while, try spending the ISO one by one.
