1. After I was playing for a fair while, maybe 3 hours or so, around 250 turns perhaps, I noticed things stopped appearing properly, quest buildings on the map were missing, some monsters too, checked my RAM usage, 3.3gb was being sucked up by Elemental, this is on win7 64bit

2. Sometimes, though not everytime, when an opponent was killed by my sovereign while he has Mantle of Fire and a sword equipped, the Mantle of Fire buff kills the enemy, it kinda dies, then my sovereign will counter attack it, killing it twice, and the combat queue will not progress after that, the game seems to wait for the dead enemy to finish it's turn, the only way to continue after that is to use the auto-conclude button, a similar issue was had with that rock worm world boss thingy, the worm would pop up, fear is cast, then it waits for the worm's turn

3. After I killed the world boss type guys, I had two, the giant ice golem dude and the rock worm, I couldn't do anything with the land that I had conquered, pioneers wouldn't work, I couldn't build there at all, maybe I missed something and it's not implemented yet? I just couldn't figure out how to get at them sweet monuments with promises of power!

For the moment that's all I can remember, I will play some moar and see what I can find! =D
