Forester,
Are you crashing when you click on the Bazaar?
I would uninstall all mods, clear out any Ini edits if you have any, then re validate your game via steam. After than fire up a vanilla game, SAVE the game. Once you find the Bazaar if it happens again, submit a ticket but include the saved game. I would also use Stardocks diagnostic tool to help them diagnose your system.
