The link to Abalathian Rock Salt is a gathering grid not a scenario. Scenario is a system built on top of basic features such as navigation and gathering. What you have to do:
1. Create a gathering preset for Abalathian Rock Salt. Make sure it uses truth, correct slot/name and navigation grid in gathering settings.
2. Select/deselect your preset to make sure its working correctly.
3. Switch to scenario, add a new chapter with ‘+’ button.
4. Add something like this:
teleport(Ok Zundu)
gatherPreset(rock salt)
gather(1)
You might want to test this chapter separately before running the full scenario. Hope this helps.
