Feral Heart

It's a map for a roleplay I've been planning for a long while and I really hope there's a way to solve this. ;3;
Everytime I enter the map, it gives me a bad token. After I enter the second time, it crashes while loading and closes Feralheart. The circle continioues on and on. xD
Other information: Map is pretty large, already deleted a few meshes but no result.
I'd be really thankful if someone knows a quick solution to this. ;u;
