I figured it out. At least I fixed my problem. Had to make the portal taller. It's now six blocks tall by five wide making the actual pass through a 4 tall by 3 wide area. The damage I was taking was from spawning in the ceiling of the old portal.
I've taken as much as two and a half hearts of damage. It's always on the same portals. Most of the time it's on Xbox One but on occasion it's MCPE on Android. This is 1.7.10 better together on Realms as of 11/27/2018. Is there any ideas as to why this happens?
I wish they would actually resolve this issue instead of just marking the thread "Resolved". Or has anyone found the post that isn't a duplicate so we can see if there is a fix that they're just not reposting per thread of similar issue?
Same issue. Anyone know where the original post is that is Unresolved since this thread was closed because it was a duplicate?
Same issue. Started sometime after the aquatic update. I'm on Realms playing on Xbox One and PE. Not sure when exactly it happened because they were sort of trophy horses and I rarely try to ride them. They were naturally spawning and I got them from a skeleton raid.
