Here it is.
After defeating Warmaster Seerus in Operation Crimson Hammer's fifth level, "Engines of War", I discovered a bug that causes one or more of the Battlepods that were deactivated for real to keep using it's laser attack right when the Grand Arsenal is self-destructing. It's quite a hinderance to Knights leaving to the sixth level, "Aftermath" Fix the bug so the Battlepods' lasers will immediately shut off after the boss battle.
Thanks for keeping the game bug free!
