Game crash with pilfering scarab

Hello,

i'm farming maps with pilfering scarab. I don't know if there is a particular combination of events that can cause this, but my game crashed on 4 different occasion when i got a boss with like 1800+ stolen cards. If i die the frist time and try to enter again in the boss area my game start crashing (i get disconnected).
I fought dozen of 1600+ boss card, but sometimes that can happen( twice on jungle valley boss, 1 time on dunes and now 1 on mausoleum).
My game works fine, but if i try to get closer to the boss area it just crashes.
I tried to lower all the settings, even closing and opening the game but nothing has changed.
