All mobs except Flying Crab Hatchers are gone again. No mods

Issue

All mobs except Flying Crab Hatchers are gone again. No mods. Latest Exp branch

Replication

1. I increased inventory space for my character (300 slots total)
2. I started New Year event once setting system date to 01/01/2022 may be this could cause the bug?

Actual Result

There crabs only in the world

Expected Result

New Year event and more inventory slots
