If the official patches are not enough, several renowned modders provide deeper fixes:

: You can now choose between the original base game wedding event or the customized "My Wedding Stories" event, even if you own the pack.

: Ensure there is only one wedding arch and a clear path to all seats to prevent pathfinding errors.

: If an event hangs, use testingcheats on and "make everyone happy" for the lot to prevent Sims from leaving due to low needs.

: Use the "Please take your seats" interaction early; it is now a powerful command that clears guest queues.

: A specific "Play Wedding Music" interaction has been added to the wedding arch to set the atmosphere manually.
