Look at the original suggestion, pretty much the same -_-' Also I support the original suggestion, Additionaly adding a message on the first page in the Vehicle creation menu would be nice, maybe make the backgroud red inside of the menu instead of just the VF screen, (because a flashing VF screen is neat but not neccesary with the original suggestion and I never used the screen, when I started playing empires I didn't even know that you can also buy tanks via the screen lol ...) A red cross like in the restricted placement area is annoying BIG TIMES if you have to fight inside of the VF, Closing doors, teleporting ppl around, trapping enemys in the vf is far to griefable and needs to much coding to be worth it (i guess), (I would love to teleport camping newbs constantly out of the vf though ...)
I color coded the vehicle counter. Red = VF Locked Green = VF Unlocked If I get a graphic to replace the tank icon we can do that instead/as well.
