The first bit is because the bot (mostly due to framelock speeding everything up so much in both great ways and a few not so great ways) is running too fast, that it gets to the next line of the profile before it can actually RUN the next line. I saw this issue in Tillers, after "Water, Water Everywhere" and had to put in a 5 second pause after dismounting from the vehicle to avoid it crashing from FlyTo not being able to mount (reports "unable to fly here"). I will start going through and adding a waittimer to all of the vehicle related quests.
As for Bloodied Skies, I'm not sure what is asking the bot to attempt to move while on the cannon. There are no moveto commands other than the initial flyto, which completed, and the InteractWith, which also completed. I don't see a call to the QB directly in the log, and after all the "cant move here" spam, it Ejects and moves on. I will need to run some tests on that to see what's going on, but I know this ran for me last week. I will look into it.
Also, Gather Bro is throwing a lot of exceptions. I would look into seeing if its up-to-date.
EDIT: Was not able to reproduce your issue. Using Singular, the QB worked as intended and completed the quest. I have added in a DisableBehavior to the CR, in case it was Demonic that was causing the issue. Hopefully this will correct this. Fix will be in 3.0.1.30 sometime early this week.
