I updated both Cartas and Norman's Sky a few days ago... however, every time I open the app, it prompts me to choose which update package I want to download. That's even if I open the app, wait for them to have downloaded, then close it and immediately re-open it.
Interestingly, the actual downloads don't take any time at all -- they're immediately finished. However, I'm still prompted at every startup. I'm on v18.3.
