LOL now that is actually a solution not unlikely to appear - players being forced to use gold if wanting to have enough room for all of their dragons, scary thought...ofc they'd lose a few players from it, but maybe the extra profit from the gold sales would cover that well hmm...
It is very ignorant not adressing this issue asap when so many are (or will be later on considering the massive flood of new dragons implemented) affected- plenty more than active forum users ofc- not really professional imo!
Edit:Not commenting the solution in above post ofc, someone mentioned exempting gold bought habitats from limit, which is nice ofc as long as it's not only way of making room for dragons.
