Aura Bug

I was doing a map tonight with my son. The map was very easy (more monsters and 26 chaos per second so nothing special). Both of us are marauders with high HP and regen.

while fighting normal mobs (no bosses nor anything special his aura gem leveled up) and he clicked the gem to level it up then clicked off the aura to redo it.

The second he clicked it off he died instantly. Bam dead just like that.

I know its hardcore and he doesn't expect to get his character back but if you could look into the bug at least we can have the satisfaction of knowing this won't happen to anyone else.

excuse his name as kids will be kids lol its sh*tIdied (I know a very fitting name lol).

Thanks!
