[GAMEPLAY] Invisible players on the Rift

I recently came across a major glitch that not only crashed my game and computer, but also brought about the most bizarre thing I've seen on league to this day:

*** Two players from my team were invisible.**

At first I thought they were disconnected; As I informed the rest of the team of this misfortune, I was promptly accused of being under the physiological effects of psychedelics -- I was not.

I loaded a game in which two opposing Rek'Sais were about to face each other. Everything was running undisturbed until we entered the game: Only three of us appeared at the spawn point. As I continued to move to the bottom position I assumed I had to play the game by myself (without the marksman). This continued until someone put a ward next to me and I freaked out. Then I noticed how the "invisible" player was in the game; yet, I could not see the character -- I could see the abilities, coins, wards, and even some of the damage. Then, it was the same for our Rek'Sai; I was unable to see his character, but I could see his tunnels, and even his kills on the scoreboard, but not on the screen!

Personal annotation: This wasn't that troubling for me as I clearly continued to play the game and "assist" the invisible players with some hooks. However, since I could not see them, I wasn't sure whether they had low health so I seldom threw my lamp into the bushes.

Unfortunately, the game crashed as my invisible friends and I were taking on the Dragon! However, I took the liberty of producing some screen shots that could support my case. These are included as attachments on this discussion.

Attachment Descriptions:

1. • "Dragon" Screen shot: Jinx and Rek'sai are there with me (Thresh). You can see their abilities hitting the Dragon and also how the Dragon is positioned against them.
2. • "Jinx" Screen shot: You can see Jinx's rockets hitting the minions. (Or perhaps evolved minions? Somebody at Riot make a phylogenetic tree to confirm)
3. • "Scoreboard" Screen shot: You can see how there are only two players with me on the map, including only two avatar faces on the left margin. You can also see the deaths from the other team, even though my in-screen score marks 3:3, it should be 7:3. There are also times on the jungle markers killed by Rek'Sai, and on the map you can see his tunnels.
4. • "Tower" Screen shot: Although this was from early in the game, you can see the problem was seen from the beginning of the match until the game crashed.

I hope I gave enough details; if not, send me a pm, or comment below.

TL;DR The game had invisible players that only I could not see. I was accused of being on drugs... and they probably reported me :-(
