Bug while going through nether portal

[TinyDeskEngineer06]

I have experienced a bug where going through a nether portal while morphing will both crash the game, and put the player in a seemingly random place in the Nether upon reloading the world, nowhere near the portal they should've exited from. It can cause players to become stuck in terrain and also possibly drop them into an inescapable pool of lava. The coordinates the player is sent to do not seem to be similar to other notable coordinates, like 0, 0. The server crashes as soon as the dimension transition occurs.

Bump, I had this crash error too and produced a log

This appears to be an issue related to rendering the player's hand, likely due to the animation that plays while morphing being interrupted

Sorry bout the late reply but I will need a crash log to debug this.

@OpenSauce04 Your crash seems related to a version of Morph I no longer support. I only provide support for Morph 1.16.5 and later now.
