Well, I'm not having much luck myself. Woke up all night every night to save up coins, at the end battle before tank, was 1/5 thus far. Went to open the next battle & I guess being so small on my phone the button for buying out the block was hit. All I could get was the tank. So much lost sleep for nothing. I don't even know how many coins that spent for the 4 battles, given that I wasn't intending to spend them, so I didn't even know what happened at 1st. I have plenty of gems & could speed the battles up no problem, yet because there's no "check" on spending things like that like there is for the gems, bam! Gone because of a finger bump.
I wanted to write, but I know I'd never have help before the event ended, I've never had any issues resolved (or answers) that I can recall anyway, & I can't even find the way to start the conversation on my phone. I had it open a minute ago, but it disappeared & now I can't even find the way to start one again. I know I'm just completely out of luck on this, but can I at least humbly make the strong suggestion to add some sort of protective mechanism for those purchases as well? I'll also add that although having any check on spending is great, I would love to see the amount lowered, or the option to do so. E.g., in the other game I play heavily/daily (Disney Magic Kingdoms), they ask if you're sure before ANY spending of gems. It's helped me countless times.
sigh Off to lick my wounds. Could use some extra ice cream over here. I so hate that feeling of doing a fantastic job (with a lot of effort) & then just losing everything you've worked for.
(2 hrs later I found a way to start a conversation again, & I've figured out that after the 2 last quests I'd have done, at a minimum I missed out on 20 orbs, if not the full 30. I'd have been able to use joker orbs if need be.)
