Rumble able to cast abilities while overheated

Strange Rumble bug | Casting abilities while overheated
A strange bug i encountered while playing Rumble. Was able to shoot an 'E' while overheating, barely making it out alive.
Came across this bug while playing Rumble earlier today, which saved me from certain death. Could be insanely gamebreaking if exploited. No idea how to reproduce it, though.
