Rift Herald bug - save herald for later in the game (way post 25min mark, when you also have baron)

There's a way how you can summon Rift Herald and keep him around for way past the 20min mark, when Baron spawns. You go to Krug camp, and drop him behind the big Krug. (see image attached)

What happens is the Herald then gets stuck behind them and cannot move out from there, and he just sits there. Then, later when you get Baron, you can go back, kill the Krugs (or just attack them to make them move), which will free the Herald. And suddenly you're pushing the lane with Baron buff, Baron buffed minions, and the Rift Herald. This is just insane.

Pls check into this issue of the Herald getting stuck. Maybe just have him teleport back to his spawn place and walk back to lane from there, if it's noticed that he is stuck and doesn't move for a few seconds.
