Feature - Add a warning message when buying with crystals


At this point it is way to easy to unintentionally open a chest or buy a spell upgrade with crystals.

It does not have to be anything fancy, just to prevent ppl making a mistake. Something like popup ‘Purchase with 100 Crystal(s)?’ would be just fine.


Yeah, as someone who just made an accidental card upgrade of 300 crystals, I second this notion.
