I’m running a hunter class with adrenal boost perk and some kind of bug is causing the predator’s stamina regen to greatly slow down for seemingly no reason. It can take up to 30 seconds to fully charge stamina. I’ve had it happen after a second wind and thought maybe the predator would be temporarily tired. Nope, it’s also happened while at 80% health. The only thing I can think of is it may be related to leaping as I perform consecutive leaps and run around maintaining locomotion as much as possible.
Once it happens the Predator becomes entirely useless without any mobility and his options become very limited, the entire fireteam can outrun him.
*EDIT
This seems to be related to taking damage. I ran past an outpost and got shot a few times by NPCs, took maybe 1% damage and my stamina was bugged within 30 seconds of the match starting.
*EDIT 2
I figured out at least one thing that can trigger the issue. If you use the right mouse function mid-combo it seems like the predator gets stuck in his “combat” state which causes his regen to slow down until he calms down. I’ve been able to reproduce it with most weapons but is very easy to reproduce with combi stick by throwing it mid-combo. The easiest way to reset is to stand still and do a melee attack, and then wait a second for the Predator to calm down.
