[Bugs/Graphics, gameplay]Lots o' bugs

Just thought it might be easier to post the bugs I encountered all here. If separate posts are preferred, please tell me; I haven't had much of a chance to beta test previously.

I'm running vista, advanced lighting off

Graphics first:

First, mysterious little ring of light to the south. On a beach, no special properties that I can see. Probably something I'm missing, but thought it best to report

The little pictures on most units aren't showing.

And Terrain is acting very funky:

Now a couple of gameplay gliches:

enchantments aren't working. They don't affect anything and don't take up a slot. I was able to summon a creature, but still no enchantment slot

when learning spells, sometimes you can get them for free.

After being sent down to take care of some bandits (save the knight quest), and loosing, I could not re-fight the bandits, although they were still there. I could even share a tile with them! Unfortunately, the game crashed from memory before I could see if I could use someone else to fight them

Finally a tweak: the AI needs to value gold a little less. I could trade materials for gold on a 1:1 ratio. Materials are a lot more valuable in my opinion
