Super confused, buying heroes but they arent there

[VooDooU]

Im having a lot of adventures that some heroes just do not get added once I buy them. It lets me keep on feeding gold into them but never show up. Can anyone shed some light on this?

Sometimes you need to drag them onto the field (from their portraits).

Well I'm guessing your not at patron variants yet so its unlikey that they are variant blocked

Some missions have other blocks on the heros you can select, so if they have a red circle or any image on their portrait they are locked for that mission type

Then the other option is your formation is full, so you can't add additional heros to it, you would need to drag the bought hero over the hero you want to dismiss to use them

And finally you might have had a formation saved, hit that formation with a purchased hero out, then swapped to a new formation, on buying the heros levels again they won't return to the field as they've already been purchased

This being said

IF you have open slots, and the hero hasn't been bought before it SHOULD pop out on the field, IF you have open formation spots, the hero hasn't been purchased yet, and your not in some mission that restricts them you should report it as a bug

I figured it out, I had reached the max heroes for that adventure and needed to drag/swap them out. Wow that would be a really good tutorial item =P
