More feedback:
This morning suffered no crashes at all. Perhaps I'm near to discover what triggers them. Going from inside the game to the main menu and then load a save, instead of direct, ordinary loading, could be the cause. I got accustomed to do this back in the day when playing Skyrim, as it was the only way to ensure no bugs would happen if loading normally.
Another reason I can think of is pressing Alt+tab, do something outside the game and then returning. Yesterday I had to do this a couple of times, thus maybe is related.
By the way, I'm totally hooked. I really appreciate much of the tweaks you have made to creatures, spells and so on. And the attention to detail is nifty. I can only imagine how many hours you spent thinking about the best way to place objects within the landscape, half hidden. It feels great how rewarding is careful exploration.
A bit of criticism, though: I found some royal griffins available to recruit inside a pirate hideout next to a flooded house, and I'm just level three. If I was very lucky is ok, otherwise I would reduce the chance to find so long lasting creatures at such early stage of the adventure. I mean, they have plenty of hit points (220) and quite high stats in general, among other qualities. So I'm worried about balance.
Now, some other considerations and minor bugs:
I love fire spiders concept, although it doesnt work as described. They're not able to make enemies burn from afar (I attacked with them from a distance thousands of times) Now, perhaps is for the good, as burning and poison effect in Crossworlds are rather potent, and a 30% chance is quite prominent. But a tiny 15 or 20% to actually burn enemies with the ranged attack should be quite reasonable.
To be continued...
