Thanks for the response! The tire is an optional quest so that shouldn't affect this. Thanks for the extra info on Coriander. We will see if we can find the problem and will let you know here if we do, but I can't give an estimated timeline, unfortunately.

It's possible that there's a chance that something is generating invisibly over the targeting area for Barkplug. Hopefully this is what's happening because if so, we can fix that. In the meantime, you may be able to progress if you try to click around a specific area like so. It seems to be a little unpredictable and tricky to hit, but if you were able to, that would confirm what the issue is at least!
