I've seen some reports that say the end gateway spawns them straight into the void. The case for me, however, is different. I threw an enderpearl into the end gateway. I did not press any keys after I threw the enderpearl in. When I spawned in the new areas, I spawned on ground, but I glitched to the side and fell off of the island and into the void, killing me. Sorry, but I have no video evidence. I understand that this may not be fixable or able to be found; Thanks for your time regardless.
