This have all been tested on PC, but might work on console as well. I’ll keep updating this list as I find workarounds. Everyone is welcome to make their contributions, but please do not share bugs you don’t have a workaround for. This is meant to be a list for people to be able to deal with the bugs in the game, not for people to flood the post with shit for the devs, you have the bug reporting forum for that.
Predator - Cannot interact, attack, sprint, jump, etc.
What triggers it? Aiming and shooting (quick scope) too fast either with bow or plasma caster. You will also hear the vision mode change sound every time you leap
Workaround - Aim plasma caster for a second or two and shoot.
Fireteam - Cannot fire, attack, interact, etc.
What triggers it? Pressing the quick melee and weapon switch at the same time or too fast
Workaround - Use the weapon wheel to change to your knife (special thanks to @Blade_Master300)
Loadouts - Sometimes you can’t edit a loadout. It’s 24 loadouts so deleting your game data is very annoying, only to have the bug eventually happen again
What triggers it? Haven’t really pin pointed it to a specific scenario, but has to do with a specific combination of gear/weapons/perks/class
Workaround - Hold down the LMB for a few seconds over the edit button. Change gear, weapons, etc. until you recover the loadout (special thanks to @FromTheHood)
Loadout reset - Your loadout gets reset after a match
What triggers it? Varies. For me is the self-revive. I’ve tried resetting the loadouts by deleting the save data, but it eventually happens again. Happens to other people with other gear
Workaround - None so far, other than editing the loadout after every match. Some users have reported that setting the usersettings.sav file to read-only helps, though I haven’t had luck with that. (special thanks to @Vargaresa)
