Cause of laggy worlds and kicking players out

So I think I figured out why many worlds are laggy and kicking people out. LEADERBOARDS. In 3 worlds of mine and another I'm working on that became super laggy, high crash rates, hitch fraction on June 28th. I deleted all the LEADERBOARDS, everything about them (ie, Physical objs that display, any script references, and the variables in the Leaderboard tab of the console).  All 3 worlds now run flawlessly. For now I can create in session "leaderboards", but they will only show historical data for those in the session based on the ppvs.  So if your worlds became laggy, kicking people out on or about June 28th, I recommend deleting everything associated with the built in Leaderboards. How Meta has not "discovered" this by now is disappointing. Good news, historical data will continue to be saved in ppvs, just not displayable until they figure out what happened to them. If this indeed is the cause of the issues so many are having i think I need to come to Connect to further explore remedies 😜🤪😎😁
