i was playing paleo quest, at quest 3 I crashed when i see the key. i logged in again...but since this time, i dont see the key again. the key is not in my hand and not at this place. I cant´ open the treasue at the end of the quest. I had clear the cache and look for the key of the A and B sims. I find it is very pity, because the game is soo much fun. have anyone an idea what Can i make to continue play? or restart the quests? thanks :)
