Ctrl clicking maps into towers destroys any already inserted map

Hello,

The situation was I wanted to start a tower map. Trying a few different rare maps to see which would yield all three precursor slots. Ctrl clicking a few different maps from inventory overrides but also destroys the map that is currently occupying the slot.

Expected behavior upon replacement via ctrl click:
Either: The map that is already occupying the slot should be moved to inventory.
Or: The action is blocked since a map is already occupying the slot.

Maps being destroyed without warning is unexpected.

Edit 1: I'm also not able to Traverse the map anymore. Hovering the Traverse button displays: Cannot access this map. Activation failed.

Edit 2: The maps were not destroyed. They ended up in the inventory of another adjacent map. And the tower can now be accessed.
