I've been doing a lot of Autumn Harvest Instant Adventures (IAs) in Gloamwood and noticed a lot of players don't seem to be aware of how to deal with the frequent IA teleport glitches.
When an IA quest is completed, a Teleport button is supposed to pop up on screen to quickly get you to the next adventure if it is a good distance away. Sometimes it doesn't pop up even though the teleport option is available. You can open the IA tab (default period key) and get the Teleport button that way.
Other times, you are just slightly too close to the next quest area to get the Teleport. In that case, just run or ride a bit in the opposite direction, then hit period and get the Teleport button. Be sure to give it a couple seconds after opening the IA tab because the button sometimes switches from Teleport to Leave. You don't want to leave by mistake.
It's usually a lot faster to do this method than just riding there.
One place it happens a lot in Autumn Harvest IAs is in the barghest cave. If the next mission is up at the Deepwood Cottage to kill vampires or werewolves, you need to run out of the cave a bit. If the next mission is in Standing Stones, you need to run deeper into the cave.
It also happens a lot in Darkening Deeps when the next mission is up in Standing Stones. That is a long ride back without a Teleport.
