That's just it, they don't seem to be passing it anywhere. After a couple of the chats, when I went to the status of the case, it had been marked as no fix available... immediately after my chat had ended. This would suggest nobody looked at it.
There has to be a way to get something in the way of status. Either "we are actively working on it" or "we looked at it, and unfortunately it is corrupted" etc.
As far as only one similar report, it looks as if many have reported this error over a period of time.... a staff writer from Gamespot even wrote an article about the problem. (I have reached out to him as well, hoping to hear back and interested to see if he has gotten other feedback.)
Also, it's likely that when this issue pops up, other league owners are attempting to get the problem corrected, but running into the obstacles I am with the support system... it's next to impossible to even talk to someone as opposed to an AI bot redirecting to a generic FAQ that doesn't solve the problem. These are probably active leagues with multiple players... so if something like this arises, it's doubtful they're going to wait several days and hope the problem might be solved (it's now a week and counting for me.) More likely after being stonewalled with what passes for a support system, they're simply cutting their losses and recreating their leagues. (If anyone else is having this problem, I would love for you to chime in.)
