Low Entry Plugins

Alright, regardless of what I choose when the pop-up shows up, I don’t see 4.12 version. If I remove (manually, as there is no uninstall option) it, restart launcher, and try installing it again, I still only see 4.10 as the only available option (I have 4.10, 4.11 and 4.12 engines installed).

Is there an offline archive I can download and extract into 4.12 manually ?

Another major issue now is that even though I removed plugin from 4.11, loading my project in 4.12 still says project uses the plugin, where in reality I never added a single node from it. How do I get a rid of it for good, until either manual download is available or Marketplace is fixed ?
