I had some issues myself when I did a quick training drop a while back with 35.21.
Had a modified Broadsword, with two mechbays replaced with three tank bays, with the doors split between the same as the canon one. It would only drop two of the three 'mechs at once (TechManual says each door should be able to drop two, don't know if StratOps changed that); and the tanks wouldn't drop at all. After swinging around to try to deploy the tanks after landing, I couldn't find any button to land the thing, and letting it stall out caused a crash.
Don't know how much of that was bugs, features, or broken files, though I should probably drop the crash log on sourceforge.
