Fix: The elevator BossBar would show up if you were standing on a bed that was on top of an elevator even though that renders that floor useless as it is obstructed. On top of that, it would show the floor numbers deducted by 1 e.g "1 of 10" would be "0 of 9". This has been fixed and is no longer an issue.
Improvement: Prior to this update the elevator BossBar would pop up if you were standing on an elevator combo even if it was the only floor. If you were standing on a single combo it would say "1 of 1", however, this is indeed redundant and the BossBar will now only show if there are a minimum of two floors in the column.
