I was in the prison dimension and found the promenade portal. Earlier I had broken the block behind the prison portal and it dropped and I moved it into my base for easier access. I wanted to do the same thing with the promenade portal but I had not generated the dimension yet and went into creative to break the unbreakable blocks behind hoping it would drop the portal. Then in creative mode, I misclicked and broke the portal itself. I tried to figure out how to get in back by using /place, but nothing worked. I am opening this issue to ask how to regenerate the portal and place it back in my world.

I figured out how to spawn it back it by just finding a different portal

Hah, yeah - the blocks are unbreakable specifically so this wouldn't happen in survival 😁

You can still get a Promenade portal in your base, though! What you need to do is:

• place a Prisoners' Quarters portal
• make sure you have visited the Promenade through the placed portal
• then use a Promenade Dimensional Rune on the doorway, and it should turn into a Promenade one!
