Multiple Gameplay bugs and glitches that I've encountered this January

Everything is described in the video, but main problem is zed's permanent shadow and blue buff not healing as I have no clue how to reproduce them.

Hand of Baron and Promote have weird effects when combined together - caster minion gets far greater range increase than he should.

Azir sometimes can't attack inhibs and Nexus with a soldier next to it. Caster minion starts shooting cannon minion projectiles after re-applying the hand of baron buff; well and a few other minor things.
