Facings will be returned to default as I recall, if you purchase any new troops. Buy your units, then deploy them and save should be the fix.
Th AI does not know about or use certain troop types. Spotter planes are one - if the scenario designer pre-plots a pass that will happen of course. Ditto Bombers, para drop air etc - strictly for one pre-plotted pass by the designer. Ditto ammo units - if in the defence, AI units parked by an ammo bunker will take supply from it, but only because you set that up. If going forwards, ammo trucks are just another vehicle to the AI. The AI does not use gold spots, or (unless lucky) arty observers, either. Still - the developed camo AI is miles better than the original "tin lemming charge" of SP1-2-3 (But I
would say that
)!
Waypoints are dropped for good when the AI abandons them due to close objective or to engage troops seen as they trundle along. Waypoints are used to move a body of troops to somewhere useful in the scenario. They are probably therefore best if the formation is advancing in cover from where they cannot see enemy to react to (in woodland or behind hills say). They are not "patrol routes". Some folk swear by them (and go into loads of detail plotting & fine-tuning them) - most others simply let the AI do its thing and use the starting point (perhaps with reinforcement used to delay things a turn or 2) as the key determinant.
Also - once a player has played a scenario he will likely have a clue about a waypoint-led flank march or such like, and use a platoon or 2 to trigger them off the path. So a flank march may just be beter done in a scenario by a reinforcements arrival - YMMV.
Reaction turns apply only if defending/delaying of course. And also see point 32 of the release history for version 2.0. (I will assume you have read the release history for each version through, as all players should do, since it is
required reading . If not - it is found in the GG under the link "Release History").
Basically - for scenario design, set the map, then buy the required troops and then do all the detail work about deployment, reaction turns etc. (It is also best to do the map first, and
save it off as a map file so that can be recalled if you decide to restart from scratch.). Also - before worrying about any waypoints, reaction turns or whatever - test the scenario
without them and see what in your scenario needs fine tuning (this could do with waypoints that with reaction set, this unit really needs setting up facing South, we could do with 4 more turns in the scenario itself and so on). Refine the scenario from this initial first draft which is simply plonking the forces roughly on the map and seeing what happens. Then add detailed tweaks as you incrementally refine by play.
Dont dive into the detail of waypoints and reaction turns in the first phases of the design!.
