Your map "Iron Mine" needs a little bit of tweaking.
NA seems to have figured out that you can glitch through certain rocks and basically have a whole team hiding beneath the floors, ready to rise up from the ground behind the enemy.
Crossbowmen are hiding in the walls to reload, popping their torso out to shoot, then going back into the walls/floors.
shitty NA admins don't care, of course
Please fix this! Entrance point seems to be near your fourth Iron Mine screenshot, they run between rocks and go right through.
