Hola, perdón mi inglés, estoy con un traductor de Google. Esto sucede a mí, ¿cómo puedo solucionarlo?
I recently found the main problem. The gold is monitored based on the total gained gold as shown in the achievements. The gold seems to have stopped updating (at least for high level players). I am now working on a workaround at least to get experience working.
Edit: i believe the total gold is saved on the server as a 32 integer. That means its maximum value is
2^32 - 1 = 4.294.967.295
which is the number that total gold freezes.
