[0.31.1] Crashes whenever Whitney's Miltank faints

[AcousticAdrian]

My friend has been having this problem lately. In his Nuzlocke file, as soon as Whitney's Miltank faints, his game crashes. I haven't been having this problem, but for him it happens every time.

Here is the crash report:

The emoticon is actually a capital "O".

I would greatly appreciate anyone's help.

Thanks in advance,
