I have pretty bad lag myself. I'm not sure what the problem is. I can't really blame it on my wi fi because i never had 5 seconds of lag every minute or two on Rog's server.
I was killing monsters and my dyed cape suddenly went back to the original hue. I then relogged to town and it was dyed again. I don't have any specifics on what caused the changed other then monsters hitting me as I killed stuff.
For those who made a mistake or decide later to change their skills. There is already a free option you should have an item that does it for RE as well to support the server for those that are impatient.
