Is is still possible to order a replacement of any card? I ordered Sentinels of the Multiverse: Oblivaeon I got stuck with printing error where I got 3 copies of Harpy’s character card. I tried to email contact@greaterthangames.com last month, but I haven’t heard anything from them. I think that email doesn’t work anymore. Does anyone have any solutions?
Thanks in advance,
That appears to be outdated. There have been developments, and the current GTG site is over here:
And their current contact form page url appears to be:
https://greaterthan.games/pages/contact
Note the lack of a dot com, which has been replaced by dot games.
This forum is kind of a legacy at this point, and I’m uncertain who’s actually running it. If it’s Flat River Group, it might disappear any moment. If it’s the new GTG, it certainly is a bit confusing.
Based on the front page of GreaterThanGames.com site (EDIT: I didn’t know it would auto-link! 
), FRG owns and manages the forums, as they’re under that domain. Given they are obviously not handing the domain back to GTG (and given how they’ve been acting like complete assholes), I am going to assume that, at some point, they will kill the forums — probably the next time someone with any authority notices the Discourse licensing bill. 
As to support for products like OblivAeon, that’s all FRG, as they own and are responsible for all production of those products to date. However, I believe FRG has stopped doing anything to help people who have issues. Late last year, I picked up a new Sentinels DE Core set that was missing a card. Every effort I’ve made to get a new copy of that card from FRG has been ignored. I’ve heard/read a lot of similar stories. It’s infuriating.
Best wishes, folks. These forums have had a great run. I’m definitely going to be sad to see them go, but I’ve already grieved, as the community here is nothing compared to what it once was. 
Thanks for the info guys! I guess I’ll see if they will do anything, but I won’t hold my breath.
