On mobile? I have an medium class mobile, giant maps getting "buggy", not created or crashing, if you are running out of system memory. Can also be caused by to many installed Plugins.
On a weak mobile, had this problem too, Gigant Maps cannot be created, app crashes. Build smaller maps/cities.

I don't see the "Huge" button at all.
