I'm not sure if this is an issue with the Hub, or if it's a change in Unity. Before, whenever I opened a project with a new version of Unity, projectversion.txt was immediately updated. Now, when I open a project in a new version, that doesn't happen before I make some change and save the project. So if go into the hub, select a project that was last opened in version 2017.3.1f1, and select the "Open with 2017.3.1p3" option, it will go through the whole "are you sure you want to upgrade, this will take a while" process. Then, if I close the project immediately, and look at it in the hub, it's still marked as 2017.3.1f1. projectversion.txt also hasn't updated. This is a bug, right?
