Cannot move anywhere besides Red fountain

I've had this bug multiple times, either leading to 7 minute restarts or one stubborn refusal to leave the game to get an afk treat.

You load into game, maybe a little late, and you try to move. Regardless of which side you're on, you'll try to walk into the red fountain. You can stop your character or cast non-targeted spells, and if the spell interrupts movement than it will stop you completely. However once you try to move again, you will diligently march towards the enemy base. From red side, you can walk around behind the fountain gate's boundaries, and you're stuck there. You can even flash, ghost, teleport etc but once you try to walk, it's towards the fountain.

The only trend I've seen has been the fact that I'll come into the game after 15 seconds. I can't recall it happening every time, but this last time I left the loading screen after time had started in game (an issue that's happened to multiple players multiple times, it's a known bug and confirmed by one friend of mine on mac).

I'm using a MacBook, if that helps at all. Also anyone who wants to comment that I should get a real computer should contribute a copypasta instead, as even that incessant spam is a more valuable contribution to discussion.
