map/path-finding issues

Some problems from RTW have carried over into MTW2 so i thought i'd mention them here to any new modders.

The most significant is explained here:

There are a bunch of others that i don't think are fixable by modders *but* they all seem to be over-ridden if the attacking AI army can reach it's target in one turn of movement so the problems can all greatly reduced by tinkering with movement distance in some way.

You can either experiment with general movement distances to get the AI moving as well as possible and/or use lots of movement bonus traits/ancillaries. (Especially important if your mods affect movement e.g roads not buildable in certain areas or lots of added forest/hill/swamp type terrain that slows movement.)

With the AI being programmed to be so aggressive, the main reason for passivity in a mod (or vanilla) is map/movement issues/bugs.

Yeah, even in my few games I noticed that AI armies still get lost in areas of negative divergence (i.e. holes) somewhere, only draining their coffers but not adding anything to their military potence.

Yup and they still often stall after a retreat. Though it doesn't seem to happen quite as often.
