I didn't thoroughly test it, I'll do that when I can actually monitor it, but after a few mins of taking a look at it, I can safely say GB2/Flightor is terrible right now.
The unstuck routine triggers every 10s on everything that the toon touches, be it boulders, trees or, yes, even nodes. 10s of someone watching it and you've landed yourself a report.
Before Flightor would "bruteforce" some minor stucks, and successfully get itself unstuck by perseverance, like a lazy player controlling it by mouse and jerking off with the other hand would, now it's that stupid zigzag every few yards...
Not a whole lot more to add. I was curious and took a toon to TH to test nodes on hills (unfortunately I didn't come across the most problematic ones in the few mins I tested it).
I think the unstuck routine triggering over nothing is a ban waiting to happen. Other than that, it does get unstuck quicker when it's legitimately unstuck.
Now, my two cents... All you had to do was revert the GB changes to land on top of nodes. Of all the "solutions" that you guys came up, the "problem" was the better choice. By far.
I'll test it more sometime during the weekend when I can actually keep an eye on it, but seriously, go back in time and make it so it lands on top of nodes until you can come up with a real solution that has actually been tested.
That said, <3.
