Ghostship alone / Entry used / please help

Hi everyone, I just wanted to talk about my unlucky experience. I was doing the ghostship today after weekly reset but i got in a room with no one. Even with full argos set, berald sailor and 1400 iLvL, I couldn’t make it in time and got my entry used for the week not even losing it. We should be able to enter at least with 9 other people or just adapt the event with the numbers??Here is 2 screenshots of my account after the event done. It is so frustrating to lose time + ressources. Just don’t claim our entry instant when we enter??? Could I get my entry back for this week please ?
Thanks !
