I know i'm breaking taboo posting 2 bugs in one thread, but not even sure if the first is even an issue or going to be one from reading other posts frogboy has made.
Had a compatability issue with Bittorrent one night, if BT was running, i couldn't open the game, it simply froze at the splash screen. If i opened BT while the game was running, it froze producing this dump file.

On trying to test it on another night, i found i had no issue opening the game while BT was running so not sure what was happening the first time, also attempting to open BT while the game was running worked fine.
804 Gameplay CTD's
Cannot build on special improvement without building adjacent structures, unlike previous beta 2's where you could build so long as it was within your city's infuence range (improvements such as gold mines and shards since we can't unlock any of the others currently). This may be intended gameplay (though i did prefer it the other way:P) so if so disreguard the firts part of this issue.
I have had issues where even having adjacency i have not been able to build and the following is a wonderful game of cat n mouse with crashes while trying to build on a water/ice shard.
(here's the save incase you wanted to play with it yourself)

Before the save i build building from my city to the lefthand top side of the shard (only half the tile), when that didn't work i built on the other half of the tile, and still failing to be able to build the shard i built one hut on the top righthand upper side
(pic provided to show what i mean by the building placement, cause i couldn't even understand what i was writing)

This gave me the ability to actually place the shard, though doing so resulting in a instant crash.

Reloaded the save and tried to place it again, this time it didn't crash immediately, though clicking on the building a few moments after placing still resulting in another ctd

When i reloaded the game again i noticed that my cpu load was sitting at 100% (both cores) in the menu screen. Alt tabbing out to see why then alt tabbing back in produced the dx error that we got in the first beta 's and another crash (since you fixed it this is the only time seen it)

I changed the game from full screen to windowed mode so i din't have to alt tab, went back in and just let it sit at 100%. It does drop down after about a minute, so not sure what the game is doing. I attempted to load the save again and just got a freeze (no dump). I think at this point i thought something more wrong than just the game (since my idle memory usage was sitting well above 3G), so i restarted, which seemed to help a number of the issues i was having.
Once back in i manged to load the game in windowed mode without issue, and place said ice shard building, managed to deselect the town, zoom in and out a few times, reselect the town, click on it a couple of times...
then went and tried to spawn an imp and got another crash:P

I got a number of other crashes with said imp spawning and general summonings, but i havn' had time to reliably reproduce them yet. For the record, this is the first real issue set i've been able to cause continious crashes with, so far for a beta i've had a remarkably crash free time:)
