What happened?

Whenever I try to ride my dragon, I get the following crash report:
The game crashed: rendering entity in world
Error: java.lang.ClassCastException: class com.github.alexthe666.iceandfire.entity.EntityLightningDragon cannot be cast to class net.minecraft.world.entity.player.Player (com.github.alexthe666.iceandfire.entity.EntityLightningDragon is in module [email protected] of loader 'TRANSFORMER' @19faa9dc; net.minecraft.world.entity.player.Player is in module [email protected] of loader 'TRANSFORMER' @19faa9dc)

For some reason, this only happens on one world- it did not happen on a different save. I do have a heavily modded game. It only started happening recently.
