soo my character died in act 5 location of river just before anya, when i arrive to pick up body, my armor Dark Adherent from the disciple set disapear after i picked it up? why? thanks for help
That is usually caused by you having something else on your body that you accidentally clicked on. It would put the other item in your stash if you had room or it would stay on the ground.
If you needed to equip items in the right order to meet requirements like STR, then that can also cause it not to auto equip.
You might want to read the Death mechanics really carefully and see if any of it helps explain what might have happened.

probably that what happened, thanks for respond, but it was just becouse i clicked accidently on item on the floor, trying to pick up my body with lots of monsters around. is there any chance for the item to be returned? thanks 
Здравствуйте.
После технических работ и неожиданных закрытий игры у моего персонажа (амазонка) значительно уменьшились показатели урона оружия находящегося на персонаже, примерно в три раза, причём оружие которое находилось в сундуке (тайнике) никаких изменений нет. Такое уменьшение показателей происходит второй раз. Дня два назад были уменьшены показатели лука, а сегодня уменьшены показатели арбалета.
Прошу вернуть всё как было.
Sorry to hear about your loss. No chance fore missing items. Even if this was caused by you or a bug in their system. This is what blizz told me about missing items/chars.
