Are you using stadium server? I had this problem sometimes when I wouldn't restore the stadium(s) to the original EA assigned ones after stadium server assignments. Also what often helped me was to regenerate Fifa with File Master or CM. Because I do tend to edit around a lot and that sometimes messes things uo, especially during career. Sometimes I would also not have proper dawn graphics/lighting when choosing to play in the dawn hours. What often helps me here is that I go into kick-off mode and choose different stadiums and times for a match that I selented (preferebally the same team that gives you the trouble in career) and also to start the match. Often the lighting here was fine then and afterwards it would be fine again in careeer mode too. Hope this helps!
