All LSMs are installed on the main launch! While riding Jaguar, it appears that there may be one more to be installed behind the station, but not sure.
Many pics on my thread below
Also, Knott's (and apparently all Six Flags parks) had their servers down for a number of hours today, leading to a lot of chaos on an already crowded day. Passes weren't loading into the app, there was no in park WiFi, and nothing was able to be scanned... so for a while, that meant no purchases of any kind, including souvenirs and tasting cards. Also no Fastlanes. People who already had tasting cards had holes punched in them. Unclear how that will be reconsiled later if you revisit later.
On the plus side, if you had a mug, they weren't scanning them, so you could get as many refills as you wanted, lol. It did seem servers came up by mid-afternoon.
