Well I have some answers for ya.

Screenshot 1 and 2, odd bug that's always been a graphical error for me. Wait until you get a general that is a movable stonewall. Even though the graphical picture is wrong they work exactly like they are suppose to on the battlefield. Odd thing is there is no way to kill that bug and I believe it's caused by a leftout feature. This bug occurs when they are born wether it be a daughter or son, so to destroy that bug you have to load a previous game before they were born.

As for those last 2 it's the mysterious blackouts that occur (modded or unmodded). I have no idea what's behind it but my guess is another leftout feature. Probably a civil war was suppose to occur but because it is a leftout feature you get this oddball blackout.

Only solution I have found is hit end turn and the next turn the blackout will be gone. Although it's always been my cities that blackout and not forts.
