Game Crashes when Attempting to Turn on "Experimental features"

[dnswodn]

Hello! My TheoTown crashes with an ArrayIndexOutOfBounds exception every time I attempt to turn on the setting "Experimental features". Nevertheless, when I enter TheoTown again, I found experimental features were successfully enabled. It appears that the bug only happens when the switch is clicked but not affecting the final result.

Crash Report:
