CTD on "special" fiend trigger

[Ganen]

I am unsure if this is a trigger by sewer slave plugin or tryout fiends, but when fighting fiends, I have the normal combat rape from brutal rapers trigger just fine, but sometimes I have a fade to black trigger, before a rape animation starts, that goes into the loading screen and when the loading screen ends, I get a CTD.

 

anyone else had this? is it caused because I already done the sewer slave event? or is it a problem caused by fiend tryouts or conflicts with other plugins?
