Seriously, OOO?

So, I just went up from my party between floors to switch weapons, as I sometimes do, and someone joined while Haven was loading (I can usually switch weapons and get back into the party before Haven loads). Okay, no problem, I message my friend and he kicks the new join.
Except now the party is restricted. WHY???
I went up on the elevator, and I want to rejoin the party I was just in. What exploit could this possibly prevent?

@Oak.. there is no reason to call him stupid. Glowing what Oak is suggesting is that you redirect your post to general discussion because it is out of context of the Suggestions forum.

maybe because u shouldnt be doing that in the first place.... it's essentially cheating if u change equipment from level to level

Please, just get your items before you enter the battle ground. I'm pretty sure it was a mistake you brought your items, but I'm also pretty sure the restriction lifted after the elevator- did it? Anyway, it's better if this was moved to General Discussion. I'm pretty sure he won't mind.

" it's essentially cheating if u change equipment from level to level"
Not really, prevailing you repay the entery cost. Still, it is somewhat underhanded.
Allot of people have gotten this. It's never happened to me. I'm sure OOO had a reason, and prehaps your case is it.
You must be one stupid kid...
(Not to be mean lol)
Put this on GD what you doing here
