I just spawned outside the fountain

Reposting on NA forums for visibility.

This just happened in a Ranked Flex game I just played: I spawned OUTSIDE the fountain area. I was just buying my items, and then I noticed a movement line towards the enemy Nexus. I had to spam the Stop button for my character to stop moving, and I did not initiate the movement myself. (I play with Minimap movement Off, so I couldn't have clicked the minimap).

A really strange spawning location bug!
