Scrollable floor selection

[kikelkik]

Often, the new scroll-feature with a blank hand on a Lift sign results in nothing but spamming the message Elevator generator says this floor does not exist. Check shaft for blockage
Because it doesn't fails ever, it's quite hard to reproduce so I just set up some different Lifts.
I could determine one reproducable behavior:

1. Create two floors with iron_block at bottom and glass_block on top.
2. Right-click with blank hand on the upper floor sign.
3. Place another glass_block some blocks above the second floor sign.
4. Scroll => Error message received.

I don't know if this quite unrealistic scenario could give you a hint why some Lifts got broke (but they haven't got any other glass blocks above or within the shaft.

If possible can you create a new world with this lift, and attach a zip file of the world?

I found a better way to reproduce:

1. Right click the sign to select a floor
2. Push the Lift button WITHOUT deactivating the scroll mode
3. => Error messages spamming until you press again on a Lift sign

The scroll mode should be deactivated when the button is pressed and/or when the player distance to the sign is larger than some blocks (6 blocks should be enough).
Furthermore, a feedback message in chat like "Scrollable floor selection enabled. Click on sign with an item for default mode." and "Scrollable floor selection disabled." might be much more user friendly.

I'm facing the same problem. The error causes confusion and many complaints.
