Similar to some of the other issues mentioned. I attempted to get tickets for ANI1688435 ([url=https://www.gencon.com/event_finder/?optAnime Game Shows for Adults! (VIP Seating)[/url]), but was denied because someone on my friends list bought me tickets for something during a conflicting time, against my wishes. And since their wishlist was processed first there was no option for me to reject their purchase because I wanted to do something else during that time. Because of this, I missed out on purchasing the VIP seating tickets (despite there being more than 20 remaining when my wishlist processed). Since that time I've had said friend cancel out his order for me, but the system is STILL showing a conflict and won't even let me purchase the ANI1688437 (General seating) tickets.
With space and demand for some events being so high, there should be an option to let your personal wishlist take priority over someone's attempt to buy tickets for you. Because I was screwed over and am continuing to face issues because someone else made a mistake and happened to get higher queue priority when event tickets went live.
