Antwerp Central was AO’d before Schilde was taken. After Schilde was taken, Antwerp Central AO stayed on and CPs being capturable, despite having no links / being backline.
Attachment’s below show town having AO while being backline, having no links and CPs being captured.
You can’t start a backline AO; And, I do believe a backline AO already going, and contested, stays going until uncontested. Then the AO clears.
If any CP’s are under emey control the system will let the fight continue .
This is a non issue
