Playing on a server with my friend, version 1.16.4. I teleported to him while he was in a moving Minecart on even ground and ended up between the rails and block. When the ground is uneven (rails going up/down) or he is not moving but still in the Minecart and I teleport half my character in in a block and the other half is out. Not sure if this is a feature or a bug but I just wanted to let you know. Thanks!
