i suggest that a option to cancel the invites to party's were added, or if that is not possible for some reason, that out dated invites are canceled, like if the party leader changes (*read example), or if the floor of the invite and the actual floor differ.

this is kinda a suggestion/discussion so i'm not sure if this is the right forum, anyway...

a real complication:
...Today i was at the terminal and invited a friend to come to my party, he was at another party so he didnt accept or reject, and left the invite be. So, instead, i decided to go with my guild, unfortunely my net connection dropped and i had to close the game cuz it just wasnt working, when i came back my guild invited me so we could go on our jelly run... when we were at the end of the palace my friend who's kinda new realatively to my guild decides to accept the invite to a party im not even the leader anymore and he does not have any vitapods or health capsules, curses, poisons w/e. we had to kick him so the jelly wouldnt be too hard, making us die.
