Two issues, one probably can't be helped

When fueling the tardim with buckets of lava, the bucket will be deleted and can't be retrieved with a hopper, maybe I'm missing something

placing a boat or minecart under a tardim will allow any entity that is two blocks or taller to enter the tardim, even if doors are locked, don't know how you'd fix that

Also had an issue were the portal in tardim would just vanish, don't know why, was just in creative so far
