Potential Issue with Xylophone patch

[STSsadoni]

I'm getting this crash whenever I play the Fan of Knives card from RatMod. Don't know if it's your problem or RatMod's, but I'll post it here for you to look at.

ZylopatchPatch just appears in the crash log because it's a part of every card being played.
I think I tracked down why the crash happens (though I couldn't get it to happen) and believe it's RatMod's fault. I'll comment on your issue on RatMod for how I think they can fix it.
