Wither Spawn Animation

BUG FIXES:

-fixed a bug that caused soul sand/soil to prevent elevators (Moving Elevators mod) from moving

-fixed a bug that caused the invulnerability time setting (Cracker's Wither Storm Mod) to not work

-fixed a bug that caused worlds to freeze if they were exited while an altar animation was playing (this happened 100% of the time, so even though it didn't cause any data loss/corruption, I strongly recommend updating the mod if you're using an older version)

CHANGES:

-made it so Wither Storms spawn looking in the direction of the nearest player

-did some optimization

-more minor improvements
