Raynor, Kerrigan, and Artanis have been reset and capped to level 5
Hey HiddenSquid,
There are a couple ongoing issues that Bliz is currently working on. One is erroneously capped coop commanders. Bliz is tracking reports about this in a thread in the TS forum. You can follow that thread for any updates.
There isn’t anything that can be done on the user side. We just to wait until Bliz fixes it on their end.
