Did you spray your spray on a wall and it ended up on a bunch of walls? If so, I have seen it before. Happens all the time on Badwater. Not quite sure what you are trying to show us though.
red spawn on the 2nd CP in dustbowl, the tag shows up twice, inside and on the rear wall outside spawn. just saying that i tried it and it didn't seem to work...
It's a known bug that spray's can sometimes appear on multiple surfaces.
Heck, everytime I'm attacking on badwater during set up I sticky jump in a certain spot and spray on a wall and it sprays multiple times.
