Ive had this -1 bug happening ever since 1.08. It happends every other day on multiple occasions and i have deleted my save data multiple times aswell and also done a game verify in the epic game launcher.
The only way ive found to solve it is to either re-queue for another game and hope it doesnt happen again, or restart the game.
Also the slow-walk bug happening to predators after the latest cityhunter patch is a gamebreaker, when using ADS with any weapon it sometimes get stuck in that movement speed the predator has during ADS and you can sometimes get out from it by equipping a different weapon and using ADS again, but its not a 100% solution every time.
