[MC-138048] Crops don't grow, farmland doesn't get wet, leaves don't decay

Hello,

I just started a server on 18w43c and after playing for a few minutes, seems like nothing grows and decays, grass doesn't spread, but water flows and animals walk around. Monsters exceptionally spawned in huge sizes and now no longer spawn near spawn.

I had tried to change randomTickSpeed to 1000 and more, grow speed hasn't changed.

Restarted the server and now 4 farmlands became wet, changed randomTickSpeed, nothing changes

Seems like if a player is around a certain location, everything stops working correctly.

While being around -335, 63, 78 everything stops working

While being around -341, 62, -98 everything works
