This has been working up until just recently. I've cleared cache folders did the thing Tony has been linking with the filters (mine was already set that way.) different profiles and everything. Hearthed back to Dal, manually mounted up.
The area the bot was trying to get to was up in the mountains in an area the bot can't get to. In order to get up the mountain, you must use grapple points. The profile has hard-coded logic in it so that during the natural questing flow that tells the bow how to traverse up the mountain using the grapple points. However - if at any point you stop the bot and get off the mountain, it will bug out because the logic in the profile that tells the bot how to get up the mountain is no longer ran. To fix this, we've added what's called "jumplinks" to the bots navigation system that teaches it how to use the grapple points without the help of profile logic. When it randomly started working for you, that's because the jumplinks were activated and it was able to get back up the mountain.
