The thing with the interactions to get water, it doesn't only say "get water" in the MCCC scan, but also something like "start crafting autonomously" and other sneaky stuff, when you click to scan for example a sink. I ended up going through the long list and turning off anything that was remotely close to what I was looking for.
There's also a search feature, to speed up the process a bit. Click on the floor after turning on the scan, then choose Autonomy Commands. Then you can search for any phrase you want.
