Loaded from the puck I smooshed into a bowl, it's soft and well hydrated now. I barely had to add any water to my lather after loading.
Based on my experience with this soap, I think when people have dissipating lather it is due to either having too much water for the amount of soap they have, or they have added too much too soon and not got the water fully incorporated into the lather to make it stable. Too much water makes the lather heavy and If it's not fully incorporated the weight of it pulls the water out, making the lather dissipate. Loading more soap is pretty much the easiest way to fix this, as it makes adding water less finicky. If you start with a drier puck, it just means loading for a much longer time to get enough soap to start with. If the puck it well hydrated it will load quicker and you'll more easily start with the right amount of soap. And when you do add water, be sure to do it slowly, and really swirl it in good before adding more.
