I just discovered that this was the case. I know it’s completely irrational, but it completely ruined the whole event for me. I was psyched to see what I was going to get from my chests before I dived into the wild world of halloween. When I found out my tonics were useless for this… I passed quickly from feelings of betrayal to anger to annoyance to, finally, being generally peeved with the game and not wanting to play. It’s a really minor thing, but I’d really like to be able to use my old tonics for this new thing.
