So I accidentally found a mushroom biome and made the dumb mistake of killing 2 of the 3 mooshrooms there without realising they won’t respawn.

Now I could either try to find another, which might never happen, or am I correct in thinking that spawnproofing the 23x23 chunk area around spawn (by turning it all to path) will then allow them to start spawning back? As tedious as spawnproofing is it’ll be faster than trying to find another mushroom biome without the seed reader, which I think might be cheating.
