When teleporting a chest or hopper minecart between dimensions, the minecart drops its contents at its source point. It arrives at the destination entirely empty. This does not happen when the minecarts moves through a portal manually. Scoreboard scores are also lost, though the minecart's custom name and other data are maintained.
- Get a minecart with some items inside:
- (optional) Give it a score:
- Teleport it to another dimension
→ The item is left behind and the score is lost
