			If the body of a sitting or sleeping AI overlaps with the chair/bed or other furniture (e.g., table), this can cause problems. The only solution is to iteratively adjust the position of the AI and/or furniture, until the problem "goes away". Specific examples:

			* ''Treadmilling Upon Arising.'' Here, an AI first sits down on a chair, then, when going to leave, gets stuck on the chair and treadmills.

			* ''Dying After Knock Out.'' If you knock out a sitting (or sleeping) AI, it may jump up and instantly die. Likely the AI is a bit into the furniture. Presumably this makes the KO'd AI flail about and physics take over; the rapid movement damages and quickly kills the AI.

Sitting During Patrol: Make it clearer that path_sit does not replace path_corner

	It is now possible to have the AI sitting down and getting up during patrolling, using a '''path_sit''' entity. You can place the path_sit anywhere, angled away from the direction you want him to sit. The path_sit ~~should~~ be preceded by a path_corner, which is where you want him to stand when he begins the sitting animation.		It is now possible to have the AI sitting down and getting up during patrolling, using a '''path_sit''' entity paired with a '''path_corner'''. You can place the path_sit anywhere, angled away from the direction you want him to sit. The path_sit must be preceded by a path_corner, which is where you want him to stand when he begins the sitting animation.

	You can set "wait" and/or "wait_max" to let the AI wait and get up after that time. "Wait" is a minimum wait time, so if you set "wait" to 5 seconds and "wait_max" to 10 seconds, the AI will wait between 5 and 10 seconds every time. If you only set "wait", the AI will always wait exactly 5 seconds. If you only set "wait_max", the AI will wait between 0 and 10 seconds.

			== Sitting Warnings ==

			In TDM 2.08, warnings have been added when an AI tries to play a sitting animation in the wrong place. The warning looks like this:

			"WARNING: <AI name> (x y z) can't sit: too far from sitting location <name of path_corner> (x y z)"

			The first x/y/z vector is the AI's origin, and the second is the location of the path_corner where sitting is supposed to take place. If the AI starts the mission sitting (using the "sitting" spawnarg), then no path_corner is involved, and no name will be given.

			To correct this problem, examine the spot where the AI is supposed to sit. Ill-used monster_clip is usually the problem.

	Mappers may want more control over where AI face after sitting down. By default, AI stand directly in front of the chair when sitting or standing. This doesn't work well if you want AI to sit close to a table, however. The solution is to use a "sit_down_angle" spawnarg on the AI. This will cause the AI to spin in the chair after sitting until they face the direction listed. They will turn back when it is time to stand up.
