Hey, I apologize. You're testing the WebGL version, right? I just encountered the same error where only the “More Ants” upgrade appears; it seems to be something specific to WebGL load. I'm working on a way to fix this issue permanently, but a workaround is to start a new game, and the upgrades should appear normally. As soon as I have any updates, I'll post them here.
Edit: this issue was fixed in demo-1.1.2 version.
