Minecraft Version: 1.14.4
Forge Version: 28.1.10

When trying to start a world created and last played on Forge v28.0.45 - v28.0.58, Mob Rebirth crashes the game on world startup. When trying to start an identical copy of the world last played on Forge v28.0.83+, however, it does not crash and loads into the world as expected.

A few crash logs:
