[2021] Scandinavian election and massive lag on big empire and big wish for asatru music

If there are no mods involved, the first one sounds like a bug so the Bug Reports forum would be the best place. Attach a saved game there that shows the problem.

I don't have time to actually play this game so I don't know the answer to your second question. Make a new thread on it in the main game forum here, hopefully the experienced gameplayers can answer it for you.
