The game starts up well, i get my free spin and so on, but when i start a multiplayer game like deathmatch or team battle, i can walk like 5 seconds, but then the app just closes and it says: "Pixel gun 3D has stopped working." I have thid literally every time. i didn't have any problems before the last 2 or 3 updates (since christmas 2016 i think). i have spent quite a lot of money on this game, so i really need help. I'm playing this game on a Samsung tablet.
