Move Command stuck on upper-right corner of the map (in Red fountain)

This has only happened to me twice ever, but what basically happened was that no matter where I commanded my champion to move my champion would begin to walk towards the red fountain.

Things I've noticed:

• This has happened to me once on blue side (first time) and once on red side (second time)

• Game did not load at a normal pace (slower than usual, but I wouldn't say slow enough to raise suspicion before joining the game)

• If I issued an attack command I would not move

• If I recalled or casted a spell or pressed S (default S command, don't remember if it's stop or hold or something) I would stop moving

• I could teleport to turrets

• All non-targeted non PB-AOE spells went in the direction of my mouse regardless of whether my mouse was towards the red fountain

• In the first game the bug persisted until the game ended; in the second game the bug was no longer present after restarting the client (I did not try reconnecting because it already takes me a long time to load into game)

• This has only occurred twice as far as I can recall but both instances happened in the last 2 weeks
