After comparing two servers of my game where one has a heartbeat of around 10 and the other 55 to 60 with a similar amount of players inside and even comparing microprofiler results i could not determine any single script in the game to have caused such an extreme difference leading me to believe that it has to be something internal that is to blame.
Roblox put in a limit on playing animations per animator which has helped but Exploiters are still able to cause some lag - just not as much as before where they were crashing whole servers.
Having the same problem since December 12. They’ll keep ignoring us It’s an engine level problem.
I hope this problem starts to happen in every game and then causes to an extereme loss of money for Roblox.
