Funny enough - minutes after posting here i did get an email from support, asking me for a screenshot of the issue - well i have none, i know i should've figured out how to take one when i saw the 200 coin price - i did suspect it could be the games poor mechanics that just hadn't updated the game graphics, but i just clicked it....game bugged out when i did, at first the dragons were out of the nest but i still had the 12 hour timer on nest(!) but then it froze again and the dragons were back in nest, and i had lost 12 gold....
Well, i don't have a screenshot so despite seeing that a few other players has had same issue - making TL well aware that there was an actual problem - i can't prove anything, and i'm not expecting any extraordinary customer management (hmm tbh i don't give them my money so cannot demand that anyway lol) so i'll just skip it.....next time i'll know better!
