On Echerion, at the respawn location in the screenshot above, you can shoot, walk and jump through the wooden part of the wall between the stone and the tarp (top left above the water fountain, basically). This is especially an issue because it allows players another way (and angle of attack!) out of the respawn that opponents outside could not possibly anticipate.
Please fix it by either removing the wooden texture/model, replacing it or giving it a collission, thanks!
