There’s DEFINITELY a problem with resetting gold & trophy amounts every week for some players.
The issue involves different time zones causing an incorrect server reset for trophies/gold for some people. We’ve actually spent hours looking for this (over the last 6 months) but we have not been able to find the cause yet.
Since we’re about to start a major guild update anyway, including the code that handles the reset, we’ve stopped looking for the issue, and we beieve it will probably be fixed when we release 2.1.
That’s still at least 2 months away however, so I just have to apologize for the continued problem in the mean time.
