Please don't exagerate figures. But how much have you accidentlyly spent playing the game to help mods understand the scope of the problem. I have accidentlyly spent around 2.5vaults of gold, about 15,000 energy (conservatively guessing) by tapping on invisible guys or accidental taps, about 4 or 5 stamina refils. And about 3 health packs.
I did get refunded a vault as I accidentally clicked finish upgrade on a vault upgrade about a year ago as it did not have a confirm. The game was lagging and bloom lost all my gold before war. Didn't get it back till a week after war. (Back when I was a spender), I twice lost out to crates as they would pop up and GReE wouldn't refund me as its gambling that I accidentally clicked on. After having previously sent tickets to express my displeasure at gambling in an unrestricted age game.
Post your stories and please do as I have and estimate conservatively or post exact figures if you have them.
Note:
I would like in settings to be able to disable the gold spend. Wouldn't stop me from clicking on invisible npcs but it would save me the free gold I accidently spend every war lol.
