I also experienced this issue on Friday, so not necessarily just a local issue. In addition to this it also appeared to be a bit arbitrary what changes were included in the deploy as well (a big quantity of changes were often missing when I tried to deploy, and only appeared after I deployed something else).
Can also add that for me, Friday was extremely unstable in general, and the ampSession error message (Create: Ampsession already has a socket - Bug reports - Appfarm Community) occured at least once every 30 minutes
