Two things that I have noticed additionally working with MS2015(applies to 2010P1).
If you open the MS2015 MFD in a DX9 EXT MFD, selects any other mode than FST (the default I guess) then... As MFD window is resized it reverts back to FST mode as it updates (whereas it should retain the previously selected mode I think).
The other is a bit more complex but relates to the orbit call in the guidance file.
I have included the scn, ini and gnc file below for retesting and perhaps confirmation of observation. I have replaced my mesh and exhaust tex files with either the MS2015 default SLS or orbiter default files so it looks weird but is OK for testing this.
Using these files as setup starting the AP will initiate launch after 15 secs. What happens is that the Orbit AP will initially roll the vessel to one side for 90 deg. (MET 0:05 to MET 0:12 approx) after which it will reverse the roll going back through the original orientation for a 180 deg roll to the final Launch roll orientation. If you look at the HDG value the AP rolls to 90 deg HDG (which corresponds to a 29 deg incl at Cape C) but in a heads-up attitude after which it rolls through 180 deg to heads a heads-down (as I have specified upside down in the GNC file) but largely maintaining the HDG due to the fact that it pitches ever so slightly back over zenith.
In general the Orbit call is a bit twitchy in the beginning which however can be dealt with - but I just wanted to point your attention to this and since it is repeatable maybe it can be addressed. (I have actually used roll and pitch MS2015 AP commands on other designs and once stable values has been achieved then letting the orbit AP take over).
On a sidebar I can mention that I discovered if I - after launch - activate developer mode - have it reread the ini - and then reset the vehicle to same position and orientation as previously...the AP will actually roll the correct way from the beginning.
Zip file with a scen, ini and txt (GNC) is attached
Best regards
