I hope you'll read this. I had no intention to sell the same update twice, and the message in the description explains the situation. It's the first time I released beta here and I simply didn't know how to update the build so that previous buyers keep having the access.
The same thing didn't happen with 0.9.1 > 0.9.2
Please, contact me in discord and I'll be more than happy to give you a link to the update. The 0.9.0 build that you saw only had around 30-40% of all content for this update, so please, reach out to me.
I'm sorry for this mess.
