I mean I am glad to see your list of updates....but how are you prioritising bugs? Its a one line fix, I even told you the file to change, and its something that has a direct financial impact on anybody using maxmind in two ways:
Anybody paying for maxmind for the last year has been completely wasting their money as the Invision integration is broken
Anybody relying on maxmind for fraud prevention will almost certainly have seen an uptick in fraudulent payments, which almost certainly ends up in a chargeback and a fee incurred. To the end user, everything works as expected, maxmind gives no errors and looks like its working as intended, but its only when you dig into it you see the fraud score isn't being used at all.
Are you going to be reimbursing customers for this financial loss, considering you have been aware of the bug for a year and have done nothing about it? Maxmind is a core component of Invision, not a third-party addon, and it is STILL BROKEN after almost a year.
