Yes (inspired by other myths of course), but most of them did not have much detail added, just a general sphere of power. Only a select few played major roles in my campaigns.

Love it, that's my kind of map!

Thanks for the report! We've noted the problem and will look at a possible fix, when FT3+ gets another round of updates/work.

No sorry, I haven't seen anyhting like this, nor had any support requests regarding a specific graphics card.

Yes, it is still a thing. Do send us an email at ralf@profantasy.com if you're interested.
