Hello! The issue was on an older full release version the game was on hard-core mode and the mobs seemed to come out of a cave? three mobs spawned. The issue is not on latest preview and the spawn location had been changed. It was a seed template for the mushroom biome.
The seed is 3903589
And the other half mushroom biome is at spawn in two chunks.

We only track issues that occur in the current release or preview version. Since you say this does not occur in a new world with the seed you are using in the current version, could you attach a copy of the affected world and list the coordinates where it occurs?
