*Update* I did some playing around and I find that if I convert the entity to a block I can then select it with the modify tool, Regular entities though are still not clickable. I think this proves there is something odd going on.
Also attempted to uninstall and reinstall, even upgraded from version 2.1.3 to 2.2.0, still will not work.
Clicking on an entity doesn't work. I can only select things with the selection box.
And when attempting to use the modify tool you get the grey cross hair but nothing is clickable.
I cant take a screenshot of the cross hair to demonstrate.
That's like it works if you clik on empty space.
If you create some entity, a line for example, you can select if using selection box, or simply clicking the entity.
