Crashing During Fate Of The Fallen

Ellos. I've been playing Wynncraft for a long time, and decided to make a new character to play as a different class.

Everything had been going well until I got to the Fate of the Fallen quest. During the quest when talking to Theorick his attack that he used on some enemies would give me this screen and boot me back to the title screen. Avoided it by running off, but a cutscene following it would cause this to happen, and I think that the quest is literally impossible to complete at this rate.

Any help?

 

Try using a version lower than 1.13, 1.12.2 should do it.

 

It worked. Thank you!
