Boron "TS 4-dock" collision issue.

[PV_]

6.20, no mods.

"Boron Trading Station 4-dock Pier" seems to have a very small negative collision coordinate of landing boxes which sticks out of the back of the module and is preventing it from compatibility with nearby module of the same size. However, "Terran 4-dock T Pier" (the only equivalent of Boron module in the game) has no troubles sticking in the same place. Worst of all I can't put Boron dock on even with "Allow module overlap" turned on.
