Good luck =)

Update 2018-11-07: Seems there are problems with these keys?

The keys are from this bundle: https://www.steamgifts.com/discussion/KEymE/otakubundle-otaku-bundle-12

I'll wait for more feedback and will contact OtakuBundle shortly.

My keys can not possibly be the only ones with a problem.

If you read this, if you are one of the winners of the GA, if your key has also been revokes and you have not yet posted a comment, please leave a comment to let me and others know.

Update 2018-11-08: I've reached out to all winners of this GA, asking them if their key has also been revoked.

Update 2018-11-08, Part 2: Seems all Insanely Twisted Shadow Planet keys from Otaku Bundle #12 have been revoked: https://steamcommunity.com/app/205730/discussions/0/1752358461524160544/?ctp=3

Update 2018-11-08, Part 3: I have just contacted Otaku Bundle through their contact formular, let's see what they'll reply.

Update 2018-11-11: So far, OtakuBundle did not reply to my contact attempt. I am closely following this SG thread and it seems there might be replacement keys.

Sorry for the inconvenience, I'll keep you posted ...
