Thanks to the other guys confirming they also remember having a bow when this bug has happened to them.
So i included the first jump, to show the stamina was fine.
Then at the 15 second mark, i pull my bow out and start pulling it back while still invisible.
But you’ll notice i went VISIBLE when i did this - this has happened to me many times when this bug occurred. I did not press the cloaking key and i did not wish to become visible, but it happened on it’s own, while aiming - so i quickly press the cloak key again - while still aiming.
Now after this, my stamina is too slow to regenerate and you’ll see that from the jumps afterwards.
