Did you refresh the roster? If you leave the roster up on the clipboard, it needs to be refreshed to show current information.
Maybe Skuzzy tripped over your cable while he was on vacation?
Being able to get a GV inside a building by the building grabbing and sliding you in like a tree that trapped you was reported as a bug back in the beta. Since it's still a feature, maybe not a bad feature since shelling/bombing the building could render the GV inside visible as long as it's a destroyable object like barracks etc. If this feature stays in can all buildings that can be accessed be rendered destroyable like town buildings? For instance the town buildings in NDisles are not destroyable but you can get a GV into them, but base towns can have a gv get into a town building, but can be bombed or shelled down. Just something to make the GV killable instead of the indestructible status now. The truly indestructible buildings need to be hardened where it will not allow a GV inside, the control tower and indestructible hangars on a V base are a good example. Will make GVers to develop more SA driving around.
I noticed that when a tank is hiding in a building, if you drive around the building, at the right angle you can see what kind of tank is inside. They can shoot at you, but you cannot do them any damage because your shell explodes upon impact of the building. It you hit the building with several HE shell you still cannot do any harm to the tank inside. . .
