So im having this problem with 1.7.10 pack Fatal error / Morph

So i have this problem with 1.7.10 pack that i'm getting Fatal error because Morph mod is bugged. If i delete Morphs then i cant join to my own server because i don't have Morph mod. When i have morph mod on it gives me that fatal error.

so how i can run my server without morph mod on?

fatal error has occurred this connection is terminated''

Or do you mean report

But can i just remove morph mod from my 1.7.10 server so i can play it?
