Ok...so first time this has ever happened to me. The other day I was playing assassin on steel peel and i juiced and ran into the other teams base. I took out 2 turrets and going after the third I lunged and got stuck in an ice trap. I smoked to blind an assault next to me and when I did I smoke jumped out of the ice trap and landed....but with a full flashing juice bar. My first thought was...oh what the hell I thought they took care of that juice bar glitch so I retreated a bit and my friend in the room goes "why is your juice bar full?" i told him "oh it's a stupid glitch, now i can't get juice against until I die....watch" So i hit both bumpers and to my surprise I juiced again! TLDR; Stuck in ice trap while juiced. Smoke bombed out (Still juiced). Landed with full USEABLE juice bar.
This is actually a quite old bug that seems to only happen with Assassin's. I know way back when I had it happen to me but the circumstances weren't the same as yours.
I knew about the bar staying full and not being able to juice again until you died...I never knew about landing with a full useable juice bar though...
