I have iPhone 5 IOS 7.0.4, 64 habitats (30 are 4-dragon habitats), 210/218 unique dragons (216/218 if you consider the 4 sitting on my nests and the 2 in storage). Awhile back I sold 10 of my 4-dragon, 500-gold habitats for 13,000 coins in order to buy habitats for dragons that can't go in one of the 8 colour-type habitats.
Crashing isn't a big issue for me. It happens a few times a day (big deal) but the lack of habitats has brought my breeding program to a standstill. My neighbours will be looking at the same 4 eggs until TL increases the habitat maximum. I am seriously thinking of moving on if we pass the expiration date on the Romantic Rock habitats. That's tomorrow!!
I'm not angry or frustrated anymore but I am weary of having to beg for a habitat increase. It's too bad because I enjoy visiting my neighbours and challenging myself with the breeding, battling, questing, summoning, etc. This really is a very fun game.
