I want to make this forum to have fun at the trolls and to also make a legitimate list of signs (symptoms) that a game is about to screw you. Think back to all of those painful WTFs and try to remember what they all had in common. I'll start with some that I've noticed and if you notice any I didn't mention, or want to deny or confirm that my or anyone else's listed symptom is not or is a sign of troll-ism. Hopefully that sentence wasn't confusing lol.
Here are some sign I've noticed:
One of your starting players getting injured or red carded within the first 20' of the game.
-Super troll sign: red card leads to a penalty opportunity.
Your first open opportunity being blocked by the GK of the weaker team.
Your GK rating decreasing down to 5.4 within the first 30'
