[GAMEPLAY]bug when match started

when match started i see all my team and me invisible....i can just buy item and go in lane. when i start to farm i can do just 2 or 3 autoattack and all minion and champion are stacks but sometimes i see all move and me can move but don t lose life. i think all the match are bugged because i restart my pc,lol client and connection but when i try to rejoin the match my champ loading but i don t see other people loading are all not connected but i can connect to the match and when i enter it s all same i can t game see al stacked but i can move. what i need to do? i lost 2 ranked for this bug. last bug it was 3 weeks ago
