1. All the videos from Crawlspace to Facade (plus two videos that haven't been uploaded yet) take place between the 2014 - 2015 timeframe. The reason how we haven't gotten a present update is due to Noah taking his time uploading the footage from what happened that year. OOG, it's because the creator, Adam Rosner is currently attending medical school which takes up most of his time in the not-summer months.
2. A thing to note with crossovers is that while they may all exist in the same universe, it's not like the Marvel Cinematic Universe in that every story is deeply connected to each other. There may be moments where they intersect for various reasons (i.e: HABIT of EMH being responsible for freeing Firebrand and teaching Noah Severance, Mary and Milo having connections to the same cult that's hunting the DarkHarvest crew, ect.), but 95% of every Slenderverse series is standalone. So while Stan Frederick is technically canon to TribeTwelve, his connection to Noah isn't all that important to this series.
