Hi, so i found out that this error is also triggered when an animal from "Legendary Beast" plugin gets killed. No i don't know if its only with legendary beast or there are others that caused this as well but I just thought I'd add this info.

Show me the error for legendary beasts please.

Have added a null/real player check for the method that calls STCanGainXP for next release. Add me on discord and we can test. im the new guy#0001
