Team invisible [GAMEPLAY]

I disconnected and reconnected myself to the game and on reconnection my team was completely invisible on both ground and minimap. Sejuani ulted from literally thin air.

Here's what I did

1. I alt+tabbed out of the game
2. Changed my wifi access point (I have a signal boosting router, and a supplied Verizon router in use. I switched from the Verizon router to the booster router)
3. Exit game
4. Reconnect

Side note!

I switched back to my Verizon router and reconnected, which fixed the problem. I dont know whether it was because I switched WiFi points or because I reconnected.
