Game Help:World Routing Lagswiki
What has been done?
Refer to the Map available in Game_Help:World_Routing_Lags/Wherewiki for the fixed spots. And the Resources thread linked above, just to see what I've done.
Backup!
Heed that backup instructions in Game Help:World Routing Lagswiki, really! You've been warned!
If you care to continue any legacy games or Saves that you care about in the fixed version, use Twallan's Porter to transfer any Sims or Household you care about from your previous Saves.
How to install?
If you don't already have the Lunar Lakes world installed, install it first.
Download all parts of the world, and rename them to get rid of the "MTS_ellacharmed_<numbers>_" portion. See Game Help:DFDD4 Download the File#Content with Multi-part fileswiki with pretty pictures.
Right-click on the file with "part1" in its name and "Extract here", or whatever command your program uses. See Game Help:DFDD5 Extract from Archive#Multi-part fileswiki with pretty pictures.
Place the extracted & joined .world file in this path and replace the default version. (You have backup, right?)
