On the modded moon Cerys, the magnetic field is 120%.
On the modded planet Maraxsis, the pressure is 200000 but has zones in which it is meant to be lower.

I think that the max magnetic field and pressure should be increased.
(Or in the case of Maraxsis be made compatible with the pressure domes but that seems like more work)

The number seems specific enough to be because of some modded planet having problems while transporting between, so I am not too certain it will be changed just for one planet. If the rings can work in outer space and pretty much everywhere except cerys and maraxsis, I don't see why they have any pressure and magnetic field requirements at all.

The rings do not have any environmental limits. Some other mod seems to be adding pressure and magnetic field limits?

Oh, that's kinda interesting. I guess I'll try figuring out what mod is causing them to do that.
Cause it has max 119 MGF and like 50000 max pressure in my world. So I'll be back when I figure out what is what

For the pressure, it seems to be a maraxsis thing. As soon as I removed it the max perssure was gone and the same is with cerys. It seems that both of them stop teleporter mods from working on their surfaces (or at least this one)

(Edit): Nope, it seems that the two add the max pressure and max magnetic field only to the transport ring...

It might be caused by the mod itself not having any requirements and those two mods automatically adding them to any structures that don't have them natively

So yeah it seems you would need to add some requirements just so other mods can't force their own.
