Restoring bunkers to full strength: WAD?

[ComradeP]

According to both the old and the updated user manual:

Abandoned Bunkers and Pillboxes can never be restored to full strength once abandoned or captured.

Lower case bunkers can be improved to BUNKER state when they start as lower case bunkers (that might be intended and doesn't necessarily violate the rules).

However, abandoned bunker hexes can be restored to full strength BUNKER hexes as well, which shouldn't be possible according to the manual.
