Common issues with Mine Cells

I am experiencing issues when entering the Ramparts

If you are getting teleported to an unusual place, or are experiencing weird behavior when entering the Ramparts, you should set the disableFallProtection option to true in the minecells-common.json5 config file.

The game crashes when I enter / walk around the Promenade

This can happen in older versions of the mod due to a bug in Protector entities' code. You can either update to the latest available version, or downgrade Fabric Loader to a version below 0.15.0.

I can't find the tentacles that Conjunctivius spawned

The tentacles can rarely get stuck if you're unlucky. They should die out on their own after a few minutes, so waiting might be your best choice.

If you're in a hurry and have admin permissions, you can use the /kill @e[type=minecells:sewers_tentacle,distance=..128] command to instantly remove them.

I get stuck in a wall / the dungeon is missing when I enter a Mine Cells dimension

This happens with older versions of Mine Cells if you have Sparse Structures installed. You can either figure out a custom config to exclude Mine Cells structures from that mod's configuration, remove Sparse Structures, or update to the latest version of Mine Cells, where a workaround for this issue was implemented.
