Thanks. It's more how regarding Humble does their assets when you buy them. Some you redeem and some they host the asset directly. It would be nice if Humble would allow updating of assets, but it seems like its stuck at the version that was provided at the time you bought the bundle. Shame since the asset bundles on Humble are $25-30 usually.
Your asset in the Humble bundle was hosted directly by humble and not redeemed on GDM. So I guess whatever version was uploaded to Humble at the time of the bundle is what people who purchased have access to download.

Oh, I see! So even if/when I update the asset, the version downloadable from Humble wouldn't update- That makes some sense, I guess. I wasn't sure how they had it set up. If you spot any others that may have been updated since you picked up the bundle and I'd be happy to generate download keys so you can get in on the updates!
