Welcome aboard.
I will try to answer your questions
1 . a. Be more careful when identifying flags. When on UZO or attack scope mode in the upper right corner of your screen there is a pull down flags sheet "Flaggen". There you can see to which nation each flag goes and if she is an enemy.
OR
b. Use the Contact color mode

to restore the colors
OR
c. Modify your bacic.cfg file as follows:
[RENOWN]
RenownReachGridObjCompleted=100
RenownPatrolGridObjCompleted=500
CompletedPatrol=150
NEUTRAL=1 Change this from - 1 to 1 and no renown will be deducted for sinking neutrals
ALLIED=1
AXIS=-10
WrongShipSunk=-5000
FirstRankRenown=100
SecondRankRenown=350
EndCampaign=-5000
2 . This happens when a contact is far north out of the grid system. If you zoom out enough you will see it and intercept it , if possible
3. There is no BF10 , a common bug. Just ignore it. In any case in GWX you don't get renown for reaching and patroling the assingned grid unless you change the basic.cfg file (See No 1c the green lines)
4. It is not the job of the Kaleun to babysit his crew. Use the No Fatigue option of the SH3 Commander.
I hope I helped.
Gut Jagd Herr Kaleun!
