Campaign manager Little Mouse handled their campaign a couple of months ago.
It has been a long time since I talked with my coins.game contact. he hasn't checked my DM in a while.
Ahh... I was about to shoot you a PM, asking for your contact at Coins, see if I can reach them and get them solve these cases... perhaps even have them return for a while into the forum [that'll be a nice thing]. But I see that it might be a dead-end too.
If you think it's worth trying and don't mind me to try reaching them, though, please send me a PM with the contact details, I'll try to nudge them.
