/cgl/ - Cosplay & EGL

>Part of a couple group cosplays for the first time, super excited
>Not my first choice of characters but really putting my all into my costumes for both, can't wait to take pics with everyone
>2 weeks until the con and people keep either dropping out or bitching about their character choice after already changing it several times, others offering their character choices just to shut them up
>Some have gone completely silent and I have no idea whether they're actually doing anything or just sick of the whiny group chat chatter
>No photographer/time/photoshoot booked for one group, get brushed off if I ask if we can finalise that

Are my hopes of having a nice memorable group cosplay going down in flames? Does it always go like this?
