Further research has been done, and I came to the conclusion that in my current run water was cut on day one, that's why I couldn't wash bandages on faucets or sinks. So, I've been drinking the water left without knowing. Maybe a notification that the water stopped running is in order?
Also, if bandages can be washed from a container, why not from the sink? Can this be count as a bug, or is it a feature?
