As I was scouting an heli crash ,I noticed that throught the smoke I could see a singular house that was visible ,it stood out like a sore thumb so I decided to investigate and this turned out to be a house that was rebuilt by a player
I believe this is not a coincidence but that ,as said in the title ,heli crashes smoke actually highlights player rebuilt structures
this could turn into an issue ,on an open map like Nasdara ,this bug could be abused by players that could "scan" multiple towns at once ,allowing the player to find bases with ease
