[Vanilla Bug] Alt-Tab "build anywhere" glitch.

[CCHyper]

Description:

When a user is in placement mode and is passing the placement checks, if the user alt+tabs out and moves the tactical view using the radar, then alt+tab's back into the back into the game, the user can place the building at this new location, ignoring all placement adjacency checks.
