We have received a number of reports of players who should have received their monthly coins. We are looking into it, but unfortunately I don't have a workaround or ETA for you at this time.
It does look like the Security Key grant has gone through alright for you, although this is of course a small part of the overall monthly amount.
Thank you Beesodd for firstly acknowledging that there's been numerous reports of the Cartel Coin problem and secondly for reporting that you're looking into it. This is the first confirmation from CS regarding this problem I've seen.
I'm really understanding when there is a problem and people acknowledge it and communicate and as a result a lot more satisfied; it's the silence that's the most frustrating. So at least some kudos for at least communicating with us.
