The Tablet in the lost tower doesn't work.

The essence of the bug:
After passing a lost tower, it marked as if it already had a tablet installed, even though there were no tiles in it.

At the same time in the neighboring tower, in which there was already a tablet, there was an empty slot in which can not be used.
