I think you did this to prevent a bug where player could teleport out of caves though this was set to false.
But now every player that has to teleport immediately can't when near a cave which annoys players a lot cause you don't always see the caves
and the radius for this is really large.
This forces players to walk a while til they can teleport instead of doing it immediately to be safe when they need to be.
If possible please work on this and make it possible to teleport above caves again.
Thank you.

What if you changed these values to like, 0 or 1?

"Cave Distance Small": 40.0,
"Cave Distance Medium": 60.0,
"Cave Distance Large": 100.0,

Did you try this?

I'm at work right now (don't tell my boss I'm on here!) but a prominent member posted this too: https://umod.org/community/nteleportation/20401-cant-teleport-or-set-home-above-ground-when-near-cave

I'm gonna find out after work if setting the cave distance to 1 still blocks caves. I would imagine "AllowCave" is what blocks cave TPs, and the cave distance blocks setting homes close to caves. I'll find out more tonight.

For now I set half the size for all caves. Will see what happens tomorrow.

No matter what I did I couldn't get it. With AllowCave False set, and the distance set to 0, I still couldn't get a home set by a small cave. The game itself blocks building pretty close to the cave entrance. I can build about 15 meters out, but can't set a home on the foundation. I have to move further.

    "Cave Distance Small": 0.0,
    "Cave Distance Medium": 0.0,
    "Cave Distance Large": 0.0,
    "Default Monument Size": 0.0,​

Bummer on this one.

Thanks guys, I might have this resolved in the next update as I've added a check to allow above ground. You'll just have to give feedback if it works as intended.

Will do. :) Just have to wait til Friday when the wipe is.
