Steam version. Roughly 9:30 CST, I hit the teleporter at the end of a Nurgle boss level in Void Crusade & began looting the surrounding chests. I paused to bring up inventory, switched armor to a red set, then found a better one in the same menu session and switched to it. When I unpaused, the game stopped responding & the Heavy Weapon Crusader froze still, mid-step. I paused again and moved to inventory and tried switching my armor back, but it just changed the appearance without restoring control. Besides pausing menu options, whether using controller or mouse, no effect in-game would happen.
