refund me now!

Literally just spent ten tokens on ten engines and got nothing. I don't know why this always happens to me!
Please give me ten engines or tokens because there is no way I'm letting this go.
This is clearly a bug and needs to be fixed right away!

EDIT: NVM it just took ages to give me the engines!
All fine now!

Was it on the app or PC? Maybe there's an issue in getting the tally to refresh live, but reloading the page (whether app or PC) updates it.

It was on PC, I refreshed a few times.
