How many days? Sometimes the RNG just doesn't want to give you what you're waiting for. Just checking, the quest The Suitor is completed, right? Also, did you edit anything or use a mod other than Spicy or Gnomes? Those two are safe to use but using other mods or editing files can bork the game.help with wedding wrecker quest? the walkthrough says to wait for the carriage to spawn with a 40% chance. but after skipping many days by sleeping, the carriage doesnt arrive at all. is my save cooked?
Something that seems to work for me is closing the game entirely then reopening it using the last save from before the problem started. This seems to make the RNG forget it doesn't like me and gives me what I'm waiting for fairly quickly. Though it might just be an illusion and I was due for it anyway.
