Hi,
since yesterday the games i need until next belt do not decrease anymore. They are stucked at 95 games unimportant how much i win. I play in official rooms all the time and i also get the 10tc per win .

Anyone know what to do?

You played way more than 100 matches. You can only gain 100 qi a day.

is this serious? you cant earn 100 qi a day? was this changed because i think it was not always like that..

It was changed like a year ago to prevent farming.

Exactly, it was changed by farmers, bots etc. One guy reached over 60000 games played with bot.
