question
 

dont really know why my battle wuz closed and why i lost and niether one of us posted??? just askin any info would be helpful.

If you both checked in, then you can lose a battle that way, and if the battle was old then it was probably closed because of time.

What The Revelation said... basically, if you both checked in, the first person to check in's drop time will be earlier than the second person's. If the first person doesn't drop by the due time, the battle will automatically close with the win given to the second person since there is no point for the second person to drop since the first person will automatically lose anyways for missing the deadline if the second person had dropped.
