Whenever I queue up for the Proving Ground strike, whether it is for a regular strike, nightfall or grandmaster it bugs, gives me an error and sends me back to orbit. - This bug occurs in the following scenarios: -1. After entering the enormous battle tank, and your fireteam has to carry the first orb to open future doors, it wont allow me to deposit that orb NOR will it allow me to enter through the door. When THIS bug happens, it kicks me to orbit and gives me: "Destiny Error". -2. When my fireteam has cleared the entire inside of the tank, and readies to take the elevator up to the next floor, this occurs almost every time: The combatants are "AFK", they are not moving nor shooting at me. They keep spawning at my screen, but not on my Fireteams. The fireteam will then move with the elevator, but it is not moving my screen. After approx. 5-10seconds it kicks me out, to orbit and gives me the same Error code. -3. IF non of the above scenarios have not happened during my run, the last bug appears. It is just before entering the chambers of the last boss. To enter that room there is a huge door that is supposed to open when getting close. In fact, this door is kept shut for me. Unavailable to enter the room, approx 5-10seconds later I am then kicked into Orbit and given the same Error code... once again. I have tried verifying game files, queue up in different fireteams with different NAT-types, tried uninstalling the game, tried different queue strats to enter the strike/nightfall/grandmaster. Non of these solutions have been succesful, repeating with the same outcome. It is very frustrating and truly upsetting. It is the ONLY instance in the game that gives me these bugs. I will be trying to get footage, pictures and other things to get more in-depth knowledge of why these things keeps happening. Sincerly, Theguub.
