I believe one of the arguments is for the colour set.
The second argument is color mode. It's a feature that Badspot never really finished. You can play around with it though. Try different integers from 0-3.
How do you use %ownership? Or is it a boolean variable?
1 - load as host's (i think)
serverDirectSaveFileLoad(%fileName, 3, "", %ownership) - For loading bricks in scripts, %fileName is where your save is, %ownership can be 0 for load as host, or 2 load as public
1 - load as host's (i think)2 - load as public3 - load as owner's (i think, again)
No, 0=host, 1=original, 2=public
