[GAME] burns my flash and autopaths me to enemy fountain upon loading in, serious pathing glitch

pretty sure someone on the enemy team tried to hack my game, but in essence my game sat at 99% loaded for around 5 minutes, (note that everyone else HAD loaded in and was playing for 2 minutes, yet it didn't wait for me) and upon loading in I find the game already started, I go to open the shop and instead flash towards it, and immediately after buying my starter items, I try to go to bottom lane (I was playing blitzcrank support after 7 unsuccessful champion selects trying to get him due to bans, dodges, or trolls) , and end up being forced to walk down mid towards enemy fountain.

I tried stopping my character using the stop command and that still worked, but every time I tried to path ANYWHERE other than mid (jungle, bot, top, even directly behind my champion), it wouldn't let me, just kept pathing me towards enemy fountain. Recall still worked, so I backed and then restarted the game client from scratch and loaded in and was good, even helped my team turn around a fed riven for the win.

Seriously, wtf is this glitch though, pathing being locked in to only down mid lane towards enemy fountain?
