Whenever someone gets downed, the bots run towards them to save them, however they do this regardless of where the tank is, often leading them to get hit and downed by the tank. Sometimes if the tank is blocking the path they will stand infront of it, trying to get by.

Does anyone know if there's a setting that can be changed to reduce this?
