A crash caused by a mod for a mod, I guess you could say that. I hope you guys don't mind that, since I know many devs hate it when a mod is causing the error but anyway...
This happens on a server called "Papilla Twist Island" or something. Whenever I join with the "Order of the Blood Rose" skin pack, I get crashed. Without it, it works alright. I really don't know why this happens
I can confirm that it is indeed server-sided, since I don't get this crash on PP.com
If that is so and devs can't do anything about it, I hope the Server Owner can. (You better)
