I believe I have the solution to this. I tried various ways listed on this forum to get Acan to speak to me, and after switching around on servers and jumping from stupid high peaks (and failing/swearing) for a while I decided to try spamming my glider around him. This worked after a few attempts. It seems there’s a sweet spot you can hit just by gliding for half a second or so around him. Warning; this is one stoned toad. He will likely ignore you for a while. Hope this works for you guys.
