If anyone cares, this was tested with Friends, Clans (the one here), and teams. For expediency, some of the functions were borrowed from other plugins, obviously with their inherent issues.
The real solution for any of you with issues in the short term is to roll back to a version that did work for you, however that was even possible. The plugin is far from perfect but is definitely nowhere near broken or unusable for most of the user base. Since the selling price is in accordance with real expectations, please respect the fact that I don't have an infinite amount of time to work on plugins as it does not pay my bills. I use all of the plugins I maintain and work on them when I can. Thank you for patches and suggestions. But, keep it civil.
