Wandering scavenger?

I figured it out. I thought the "Comit" button would move me past him. Why not call the shop or visit button instead?

The commit button is there because there's certain paths in the map that lead to either a wandering scavenger or a data disk node, and you can only choose one, so you'd need to commit to the shop before getting access to it. I guess it is kind of weird for there to be a commit button if the shop is the only way forward, but my guess is just that it wouldn't make sense to have a different UI just for that scenario
