[0.98][Bug/Graphics]

A few things I noticed:

1. When I save the game and the map is zoomed out (cloth map) the cloth map disappeared and a zoomed out regular graphic appear.
2. Sometimes NPC's are invisible on the map even when my army is right next to them. The mouse cursor however does change when moved over the spot where the NPC should be and by clicking the NPC can even be selected. This happens with all types of NPC's: bandits, heroes and enemy armies. I'm still trying to figure out when/how this happens.
3. Memory usage is rather high. I have a little gadged on my second monitor that displayes memory usage and during gameplay is rises from 39% before starting, to 64% at the start of a new game to 72% after an hour of play. (this is on a 4GB 64 bits windows 7 system). I have no idea if these values are normal or not. If you need more info, I'll try to get it.
