Randomly losing trophy points

I've lost a few trophies without playing a game and thus not losing one. Also this is not the end-of-season reset, which is in about 3 days.

I've won a game at 4064 points and got 30 points = 4094 trophies. Then after a break I played a 2v2 game, which does not count towards trophies, and another ladder game:

But instead of 4094 I started at 4047 and won 30 more points, ending up at 4077. This means I lost 47 points without losing a game. Surprisingly, this is the same amount I'd lose with a season reset, but it's still a few days until that happens.

What happened to me here?

Solution 1:

Almost definitely a glitch. Definitely report it to Supercell. The only possible explanations are:

1. It's a major glitch that physically changes trophy count, and therefore must be fixed immediately

2. It's a visual glitch, that is just a minor bug that causes the trophy count to appear wrong

3. Somehow the season reset happened early

Since you won both games, there is no way your trophy count went down. Maybe there was a balance change, and the leagues were changed up? (didn't see any, but then I haven't logged in for a few days) (also Wizard lvl 8? you are already dead)
