I did that BTW this is also for 0.6.0 I wasn't allowed to choose that option for some reason
That would be modded kind sir you are using mcpe in a way not intended by the developer. I doubt seriously mojang would spend their time "fixing" a bug that wasn't due to something they did.
Sorry nope nothing spawed. I’ve recreated the world (same seed) and used locate to find the stronghold location. It’s the same place as in the realm, only in the realm its not been spawned/created. The Eye of Enders also lead to the same location. Checked the other key locations and they are two undersea monuments and the abandoned mineshaft. Need to get the end portal stronghold spawned at the right location on the realm. Perhaps it was overwritten during a version update.
