So I'm running into the same old problem that used to occur with the preset object: you create some objects, create some presets, then create some more objects, then create a few presets with them. The problem is that the old presets don't know anything about the new objects, so they have a bunch of unset values.
Is there a way to force pattrstorage to re-save all current client values for a slot? I'm using the preset object in conjunction with pattrstorage and it is definitely a no go. (Max 6.0.4)
