While I was trying to figure out how to spawn in a rideable horse, I stupidly used "entity.spawn horsespawner". Thinking it didn't work, I spammed it and now I'm stuck with horses regularly spawning outside of a base, and I have no idea how to remove the spawners. Does anyone have any idea? I tried restarting the server and they're still spawning in.

You could try running the console command "del <prefab>" to delete them.

So in your case: "del assets/prefabs/npc/bandit/horsespawner.prefab"

Keep in mind this will delete all the horse spawners on the map so this could cause other problems.

Thank you! I'll give that a shot. If anything, I can go around and add spawns in other locations, just as long as it gets rid of the 4 in front of this player's base

Sounds like it might break the stables.  Let us know how it goes.

It worked! It did also remove the horse spawners from the stables, but those were easy to spawn back in. Also had to go around the map and plop a couple random ones, but much better than have 4 outside of a base. Thanks again!
