tower already used bug when trying to insert tablet

When trying to use a tablet I get a "tower already in use" message.

In standard ssf.
I am trying to use a tablet to influence the 4 remaining maps near the tower. Tower was completed before 0.2.0 but no tablets were used.
I tried both new and old tablets.
I want to irradiate a corrupted boss maps for the altas points.

Same problem(

Basically same problem.

Just completed a tower map using a 6 mod waystone. Trying to use 3 tablets in it but getting the error message "tower already used".

There are quite a few maps without any tablet modifier on it in range.

There is one tower close by which has been completed (and assembled with a tablet) prior to 0.2.0

Edit: also tried to use just one tablet but did not work either. Tried a single precursor, ritual and delirium tablet.

Same issue

Exact same issue, cleared a new tower, same thing. I can not use any precursor tablets in any towers it seems until this is fixed.
