Absolutely the same thing here. I'm really disappointed that I wasted all my topaz to get a rod that would help me get to 155 tokens on the last day so I could get the suitcase...only for all of that to get completely wiped the moment the event is over. How hard would it have been to release an update to the game PRIOR to the event ending that removes the suitcase as an option so we could spend our tokens on things that still exist in game?
The dev didn't actually want to update the game yet, the only reason they did is to fix a game breaking bug that triggered when the event ended. But I agree, it should have been better advertised. The plan was to still wait a bit, which would've let people use suitcase for at least a little bit before it was nerfed.
