It’s 100% the CCS fault, but mostly fueled by the mod on reddit aka ofrnxmr on Matrix (previous owner of AgoraDesk.com and LocalMonero.com). What’s happened is basically, he has managed to convince Monero core that despite having done all work as described, I shouldn’t be paid. It’s a total scam on their end, mostly due to core’s ignorance more than anything though, I don’t blame them as much as ofrnxmr.
Tbh dude, if they just paid the milestone, there would be nothing to wait for any longer.
