Ok, so I learned something pretty funny today, so 1) there is no setting for minecarts on your island and 2) anyone can place minecarts on your island, trusted or not. This is uh... rather odd, since if they place a minecart they cant actually get it back, can we make it to where we can choose to allow others to place minecarts on our islands or not? (it breaks roller coasters...) Also, ty SauceBoss22 for pointing this out! But yeah, making roller coasters and due to this anyone can just come in and ruin someones coaster (or auto farm)...
Support, it seems a similar thing to boats. They could be placed without the island owner’s permission before it was fixed.
Support. I'm planning to use minecarts in my pigmen farm so it'd be nice if others weren't able to mess with it while I'm offline or AFK.
