Delirium rune word bug

when a mercenary turns into a delirium, the game has an 80% chance of crashing for everyone who is in this game…
Fix it please

Happen to me also when using act 2 mercenary with Delirium runeword helm. With act 5 mercenary deos not happen. yes, act 5 barbarian are weaker than act 2 merc, but at least Delirium can be used.
The probelm with act 2 merc is that he hits lot of time in a qucik sequence and that’s why cause Confusion from delirium(or other procs) to proc one onto other and crash the game.
