OlderFart are you sure you uploaded the correct one? It looks to be the same default path than in my archive (with the same issues)
The issue with picking up quests seems to be archebuddy-related, so nothing I can do about it I think. For the pathing, I think it's also AB-related when you have a mount going a bit too quickly compared to how often GPS system must be refreshing coords (and it doesn't skip points that it doesn't get exactly on top of)
And I'll double check mount raising code to see why it goes away without finishing to raise it.
For the mount selection, it looks like I might have screwed up and uncommented a line in the detection to keep it inactive while it doesn't work. Look for "mountName = item.name;" around line 419 in the DetectMountName() function and add "//" in front of it so it keeps the one from settings line (don't forget to recompile)
