This just happened to me on an Xbox Series X. (June, 2024)
Error: the game is saying "check on the mantis" but I cannot.
-Fast travel is disabled.
-The Mantis did not appear.
-The characters are in the saloon doing old dialogue.
-There was a action dot on the empty platform but I did not use it to trigger the cut scene.
I managed to solve it. Forums like this helped.
I returned to the area where nekko riding was introduced
-I rode the first nekko all the way back to town
-this triggered the visual of the Mantis landing
problem solved
when I did this I learned I had skipped a part of the nekko tutorial:
-at the gate where you learn to do a double jump, I continued and hopped on a new nekko. But when I redid this section, I hopped the gate, turned back, and realized you could open the door to let your original nekko join you.
My theory is that the door opening is key for the game to understand the nekko tutorial mission is complete, trigger the next mission.
what did not help:
-I completed a side mission to find the musicians. That did not fix it for me.
-I went into the Alignment Control Center. Interacting with the spinning cylandir caused a 'dangerous error do you want to proceed' warning. I did not proceed.
