I'm honestly not 100% sure what's going on with the emails you sent; I have nothing from you either in the events email box, or my personal email box; if you could try to email both just so we can see if there's some issue with those, let me know; but I know I've received emails from you before, looks like the last one I have is in 2018. ,I'm sorry if the Events inbox is eating them, but I really don't see them.
Also, I'm not 100% percent sure what the issue is with your events; but I just went and looked at all the edit history now, and they correctly had a cost; but that cost did not update until they were changed from an "In Progress" status to a "submitted for review" status; I'm wondering if maybe that was the issue, that you didn't realize they were still in progress and not submitted? That would explain the cost being 0.0 from Gen Con, as it wouldn't calculate that until the event was actually submitted.
Anyhow, let us know if there is any problem with them now, and absolutely feel free to email me personally to discuss this matter further; we definitely want to make sure there's not some larger problem with the system we aren't aware of. Thanks for bringing it to our attention!
