Lunatic Mall crash

[Hammer Wizard]

I was doing my Monk run, was forced to walk away from the Lunatic Mall fight for a moment, but when I reenter the fight, the game shortly crashes afterwards.
Reloaded, crashes.
Reboot game, crashes.
Come back days later, keeps crashing.

I will attach the file to a Google Drive link, will also post the crashlog:

My computer is not exacly powerful so it probably is a performance related issue.

Took 3 tries for me to get it to crash and I've found the bug and fixed it for the next update.

Try reentering a number of times until you make it. All those caltrops and gas are messing and slowing down the game terribly on that map.
