Every time I put a coin through I get the same error. However, since it seemed to be working in the backend (i.e. giving me achievements) I kept using coins to see what would happen.

I put in 50+ Slots Coins, but I only got 200 special spins for Slots. I did get a ton of achievements though. I put in one Gold Special Coin, can't tell if that one worked or not as I got no sP, item prize, or achievement. I put in one Blue Special Coin, which gave me an item prize and the Lucky Find achievement.

I used one each of the 9 different coins, No achievement.

I have the same issue. It does seem to accept them and give rewards accordingly (slot boost only goes up to 200), but the display just isn't working.

Yes it is going through, but looks like this.

I put in 2 red coins and got the same error, but recieved a sticker and The Lucky Find achievement shortly afterwards.

I got the "something went wrong" error, and it ate my coin (a blue one if that matters) without giving me any prize. It's also not showing that I have progress towards any of the achievements, when it was showing progress when I used it previously. I had like 7/9 types of coins used, and now it doesn't show any.

Edit: lol never mind the second part; I just went to my inventory, and I won a Purrglar and got the Coin Collector achievement. But I did get the error message first!

As of today this seems to be working properly! At least with the Slots Coins.

I just tried a silver coin and got the errors above. I'm unsure if I got sP or a stat boost. No item is in my inventory.
