Done I have been crashing as well

Please remove all client-only mods and try again.

 

Only problem that there is no config to change that.

 

@PrincessJoice did you click on a dragon egg or how did it occur?

 

Oh, I thought they have spoken about the vanilla egg, I wasn't aware that it does have the the dragon mount mod.
You can indeed change the ID of the dragons mod:

Code:

	# Overrides the entity ID for dragons to fix problems with manual IDs from other mods.
	# Set to -1 for automatic assignment (recommended).
	# Warning: wrong values may cause crashes and loss of data! [range: -1 ~ 255, default: -1]
	I:dragonEntityID=-1

Issue fixed now.
