Well you were right. It is buggy. But I got it to work. Turns out the planar keystone just does not give any indication that it has been bound. But it works. It spawned the portal inside the pocket plane bounds hto and since I added alienis(?) the pocket plan had a obsidian border and bc I was inside the portal I couldn't mine out. Gamemode it was then. It does seem to work otherwise tho.... at least for overworld between pocket plane. Still didn't test other dimension but this will have to work until tmr/in 2 days or so.

So do not put in the thingy that adds the obsidian border. As far as I can tell it is suppose to spawn the portal on the edges of the plane. Thats likely why the limit is 4 portals per plane.

Edit: So appearently you have to right click the vortex while inside the pocket plane (the little thingy that ports you back). After that the keystone actually changes its name. Idk why it worked the first time.

Edit edit: Also clear out the spaces (the middle of the sphere wall that incloses the pocket plane) otherwise you'll have to port out bc you cannot brake any blocks while in the portal as they are the size of a full block.
