I was wondering if purchasing past holiday packages through support was still an option? Had a city mate who tried, and got the response of:
"Special packs are only seasonal and of limited time offer. There's a good chance that they will come back next season. News and events are posted on our official forum page."
Based on advice from both forums and other city-members who had bought packages from support, he had bought the required gem packages for the trade already. I know you have said before the offering of these packages through support could be stopped at any time through your discretion, but I hadn't heard anything about that no longer being offered. I'm not sure if that's the case, or if this was simply a case of miscommunication somehow.
You make it sound as if it's going to be hard
