Alien pq glitched?

I don't know if this is true but yesterday and today me and my aran friend traded and we were both locked out on both days from end boss room. So when you're in resseruction cube just drop the item you want to give instead of trading it. I think this is what causes one of those countless glitches sigh. Yes, I failed again today Liya . Come on more .

wow locked out of end-room for trading? Weirdness. Goddammit Nexon, get off your lazy ass and fix this bullshit.
