Summary0002414: Problems caused by interleaved thinking
DescriptionTwo problems are caused by interleaved thinking.

1) If the frame interval is high enough (>=12) it's possible for AI with doors on their patrol routes to encounter problems at the doors. The IT code can place the AI in the path of an opening door, knocking the AI to one side with high velocity and possibly causing damage. This is the cause of AI mysteriously dying "for no reason" in Heart of Lone Salvation, The Alchemist, and St. Albans Cathedral.

2) At high frame intervals, AI can have problems at path_corners. The path prediction code can cause AI to wander in the vicinity of a path_corner, constantly seeking it but never reaching it.
Steps To ReproduceGive patrolling AI on interleaved thinking frame intervals greater than 12. This brings out the two problems.
Additional InformationI (grayman) have a fix for 1, and am working on 2. I'm filing this issue before having a complete fix so that I know the issue number, which I put in the fix comments.
