Overview
Are you stuck on a infinite loading screen?Or maybe you did your first stage and can’t pass the results screen?Or your game is simply crashing as soon as you start the mission?Well look no further as I got the fixes right here.
Stuck on the loading screen
I personally had this bug and I could play campaign just fine.
What you need to do is verify the integrity of game cache. You do this by going to your game library, right click the game and choosing “Properties”, then in the next window that pops up click on the “Local Files” tab and click the “verify integrity of game cache” button. You won’t be able to do anything till it completes so just sit tight. After it is done it should download the corrupted/missing files. This fixed the issue for me.
Stuck on results screen/Crashing when starting a mission
Simply unplug your internet cable/disconnect the internet before starting the game, once you are in the Raid Mode lobby (the place where you do all the preparation) plug it back in/connect to the internet and you should not experience any more issues.
If however you wish to play the daily mission, then just go back to the main menu and enter Raid again this time without disconnecting from the internet and it should be there and available. If you crash after doing the Daily mission(s) just repeat the same methord once again while not being connected to the internet. I had this issue as well and after personally trying this I can say it works.
Low FPS/Freezes every 2 seconds
I should probably not even need to say this but simply lower some of the graphics settings, preferably effects first, if that does not help then textures as well. And if you still got trouble then simply lower the resolution. A lot of people tend to ignore the resolution but lowering that fixed the freezes for me.
