I really hope this does not sound like a general complaint, because it isn't.
I (and probably many maplers) usually afk in town whenever they are not actively playing to get the films reels, which ultimately turn into pop coins for the event. It gives a good amount as standing in town for ~4 hours give around 40 coins. However, due to recent maintenance, I'm sure many maplers including me lost some opportunities to get some late-night coins due to the unscheduled maintenance.
Now I know the GMs don't want to bring the server down to patch it up as well and so it's not being done on purpose. Because of this I usually don't comment on server being down; it's something that can happen. However, in this case there is a huge event going on with those high-tier rings, and especially without 30% discount (which KMS did for this event) some of us (yes, including me) might not have enough coins to fulfill the plan and get things we wanted to get.
Supported or not, it would be nice if someone gives a feedback on this to see how feasible this would be, as I do hope this really works out.
