I found another post with the same problem i have :https://mcreator.net/tracker/issue/44985 here it says its fixed in 2018.
However i think it may have surfaced again.
I made an custom dimension with the end generator. when i go through the portal in (either creative or survival) im not spawned on the other side in the portal, i spawn near the portal in a radius of a 15 blocks or so. sometimes i spawn not even with blocks under me and immediatly fall to the void.
i cant find anything in my dimension settings that can prefent this from happening. any idea if this is the same bug as 2 years ago?
