You could still sign in(& out) people after the battle started if you didn't close Strat. roster page.
Players who was removed from battle roster don't get XP from battle & don't have record in participated battles. But still could fight(if they won't try to reconnect).
We found this bug on todays battle:
http://c-rpg.net/index.php?page=battlesparticipated#!?page=battledetail&id=1611Druzhina_Malika was removed from the roster after she joined the battle, but she still could play till the end of the battle.
Autobus & some other guys was signed in after battle started. they joined server, got XP & have a record in the participated battles list.
Possible exploit:
open 2-10 battle roster pages & sign 100-500 players on your side. of course half of them won't get any XP, but you will won the battle
