I did the valley mission last night, which unlocks the missions you can buy. I bought them, then logged off. I just logged in now, and the "under the valley" mission isn't there at all, and the valley mission shows exhausted. What's going on and where are the missions I paid for?
You're missing Beneath Tcotzac on your map, which should be just below Valley of Tezkal? I have not heard any reports of this happening to anyone else, but the devs might want your account name to be able to check up on this on your account specifically (post it either here or mail support@cardhunter.com). I think the flagging of the unlock can have broken for some reason - but your purchase can have gone through anyway. Let us know if repeating the mission causes it to appear properly (and unlocked) once your adventure timer is reset, if that happens before your situation can be investigated. I'll leave the thread here, since it's possibly more a bug than a support issue.
