I'm not sure which one this bug is related to, but I've been able to replicate it with this combination. Can someone confirm if it's a problem with Thresh or the Talisman item?

Twice now in two days, I've played Thresh botlane, and my typical build order is start Ancient Coin, build a sight stone, maybe buy a flask, and then finish the talisman. Except when I finish building the talisman, I can't use the other activatables (blue sightstone or flask). The sightstone works again when I upgrade it to ruby, and the flask EVENTUALLY starts working again, but it's really frustrating when I can't ward or heal for like 5 mins. Maybe it's just a problem with my computer, but I really doubt it. Can anyone else confirm?
