Hey, whenever my friend and I play on moon and we are having a good game and go for rounds 30+, the excavators glitch up and block off half of the map. We hack the control panels and they go back and next thing you know its still excavating and breaches the tunnels, we go over there and there is nothing apart from an invisible excavator thing, you can throw grenades and shoot through it but it just kills you like a regular excavator. Has anyone else had this problem ? and is there any way to by pass this somehow or get back to the biodome/ ak74u area after going to earth and back ? Thanks in advance.
