I play this game since last years, i have quite high level of goods, i use kits to upgrade them until level 10,and they always stick with my character. It's been a long time (about half years) i didn't paly this game, today when i reopen this game, i realise the goods i upgraded to lvl 10 come out with a notice that trial end in 10 days! What mean is this, i have equip them one year ago! And i spend so many kits on them!
