First, when i was about to go to the End, i eyed myself to the stronghold, just to see there was no portal. I copied the world to creative, blown up the whole thing, and there was still no End portal. I've made a couple more worlds just to test it and neither had an End portal.

These happened in 1.11.0

I've tried again in 1.11.1 to see if that fixed it, sadly It didnt.

posted on r/MCPE, searched on the internet, and it looks like nobody has this problem except me
