I'll take that as a good thing. If it was trying to get back at me I must have been winning or doing something right and it was just jealous. :)

i only see dlcs for techwars when i want to create a giveaway for the game - am i missing something?

I confirm: I had an unused key from that bundle. Tried to activate. Said it's a duplicate.

Thanks, it's nice to know it's not just me. There must be a logical explanation to what happened to those keys, then...

Same here, good thing I used it right away:)

Yes, we did corporate with Groupees for this bundle, we received some revenue for those keys but of course much less compared to our regular revenues

and xcloudx's comment below.

I'm reading between lines and I might be mistaken, though. But the dev deactivating all unused keys (activated keys seem to be fine, since no one has noticed that it was revoked from their accounts) is a moronic move which, unfortunately, is becoming more and more common lately.

EDIT: The OP for that Steam thread was also intriguing:

Did they pay for those Divinia Chronicles: Relics of Gan-Ti keys ?

Good, their response to me was that they can't help after 30+ days passed, ask the dev. Apparently there were so many complaints that they had to look into, good! (I can live without that game, but it made me sad when it didn't activate)

Well, since he was b****ing about the amount of money, you should feel good about it. You gave him such a small amount of money that he's pissed off and mad about it. :)

I love a story with a happy ending. :)

Keep in mind no dispute whatsoever has thus far been indicated (including any complaints about money- the linked comment clearly indicates that developer knowingly and willingly gave up normal retail pricing so as to reach new customers through Groupees, and was satisfied with the outcome. No dissatisfaction with finances (or anything else) is indicated in that comment), and it wouldn't be the first time old keys were accidentally deactivated. Could also have just been a shortsighted move not aware of the game trading/giveaway/etc communities, and assuming all unused keys were floating around for the purpose of resale, and wanting to inhibit that.
There's plenty of basis to explain the circumstances that doesn't reflect negatively on anyone involved, and there's no evidence yet of anything untoward [Ed: in terms of the intents or policies of the developers or Groupees] having occurred.

A certain someone jumps straight into negative-toned overreactions every time there's an issue with a bundle game (and has thus far been proven wrong about the circumstances each time), so- as is always a good idea- don't read too much into the situation without actual evidence toward something.

Flip side, if it does go that way, then by all means- remember that negative feedback on Steam can be a very compelling way of changing the policies of developers.. or of warning others when developers are unwilling to change their policies.
