Hello all,
This is Noahguy, and I have noticed that when one enters a nether portal, they are unable to use commands which is extremely annoying as either one has to painstakingly break the obsidian or get a mod to help them. Also, I propose the idea that players can use commands while in a nether portal.
I agree with you, there's no reason for that to not be a game feature.
just know that this has nothing to do with arch but instead how minecraft works..
