Universal Spawners

There are no restrictions on what mobs can spawn in what biome through a monster spawner

do you want naturally generating dungeons/mineshafts to have a random mob?

Nah- I assumed te same but taking spawners in some random biome, they do not work, but taking the same spawner to the correct one they do, so just assumed there was some issue with biome.

interesting

what software are you using right now?

sorry what?

Are you talking about placing vanilla frog spawners in a desert and frogs not spawning?

Yep- a blank spawner throwing a frog egg into it

Most recent PaperMC (#222)

uh thats 100% a bug

what happens if you try that?

That's exactly what I am doing.

send a quick recording of what happens

I haven't touched MC since 1.15~ atleast, so just assumed it was a new "feature" :/

or a screenshot of your setup

throwing? You mean right clicking right? And you are using the spawn egg, not frog spawn right?

Not on right now- but it's exactly as I described. Blank spawner on ground with no other blocks around it, just under it, egg going into it to turn it into a XXX spawner, nothing

Yes lmao, the entity appears within the spawner
