There are a few bugs in secret base that I feel need to be addressed. There is an occasional bug that when you spawn, you will take damage for no reason, even before entering the start door. Sometimes entering the blue portal will take you back to the place where it is instead of secretbase. This is because of full servers. But sometimes it will kick you out for no reason. Death Drills sometimes don’t go the full distance they should, and that can be annoying when they go to a hard to reach area.
This has been addressed before by the developers. Abyss Walkers in the Nether, and Death Drills from the secret base use the same AI, and they both have the same issue. From what I remember the developers saying, it’s because of server lag, and it can’t be fixed as a result.
