In *Kingdom Come: Deliverance 2*, completing the "Wedding Crashers" main quest can be tricky, especially when it comes to congratulating the newlyweds. When it becomes evident that Otto von Bergow won’t be attending Lord Semine’s wedding, your focus shifts to wrapping up the quest and finding a new way to meet him. To finish the quest, you must congratulate the newlyweds before leaving the celebration, but finding Agnes and Lord Semine can be challenging as they seem to have disappeared.
Before you proceed to find Agnes, ensure you've completed any other tasks you want to do at the wedding. Once you start your conversation with Agnes, the quest will progress towards its conclusion, eventually leading you to Trosky Castle. Most of the extra content at the wedding happens before the ceremony, so you should be ready by the time you need to find Agnes.
While interacting with party-goers, you might ask about the newlyweds' whereabouts, but since no one knows, it's best to skip this task and head directly to where Agnes is located. If you previously stole schnapps from the wine cellar, locating her becomes easier.
