time bank vanished

Was in the middle of a cash game and noticed my time bank just vanished out of nowhere, even though I hadn’t used it all up before. Usually I’m super careful and only tap into it when I actually need a couple extra seconds. Didn’t have any connection issues or anything funky on my end, so now I’m kind of stumped. Has anyone had this happen? Do some rooms have new rules or cutoffs I might’ve missed, or is this just a glitch?
