As of game version 1.16, this mod is now obsolete! Tyron graciously included this fix in the game itself, so this mod is no longer needed. It's only useful if you are still playing version 1.15.

A tiny server-side mod that fixes an error in the game's entity spawning API.

This is useful mostly for mods that manipulate entity spawning, like The Nightwatcher. Without this patch, the game can only support one such mod at a time, and not very reliably. Fixing this bug also makes these vanilla features work:

• Raccoons can only spawn near log blocks
• With Harsh Winters world setting on, sheep will not spawn in December, January, or February
• Butterflies will not spawn in climates where average year-long temperature is less than 10 C

This is a server-only mod, multiplayer clients do not need to install it.
