{Gameplay}/{Crash} Can't see the enemies

I couldn't see nor attack 2 members (Kassadin and Rengar) of the enemy team while playing as Kindred. My team ( Fiora, Zed Tahm Kench and Ashe) didn't encounter this problem. My W was able to attack the 2 of them. i couldn't mark or see them when i pressed tab and they were fully able to see and attack me I was able to see their skills. Then when i was running toward my raptors the game crashed and Bugsplat apeared i relaunched the game and the issue was solved.
