There's a bug that has been around forever and it's really annoying and gamebreaking
When I hit "undo" in the shop because I bought the wrong item......MY HEALTH AND MANA REGEN RESET!
Pls fix this, so annoying. Takes that much longer to get to lane and there really is no point to it.
"oh, you accidentally bought 2 pink wards, we better subtract 500 health from you for returning it" - greedy shopkeeper that is STILL hording mana pots.
