i tryed to defend 50, could not connect to update server (there were message, did not copied that sorry)
then i could not defend couse it says i am already in battle
so i check/uncheck available for playing
then i tryed defend few times, all times scan bar dissapear pretty fast, and i got a free win
Edit: now i found myself chargin attack on 152... probably guy titoumili add me in squad and i left squad in some key moment T_T
as he said "i had you in the squad after i attack the planet"
sorry, i have no idea what is happening
