When I change the language of my client and log in, I get duplicates of the professions and currencies in the other language.

I made significant changes to the code over the course of the year. A lot of it was impact performance and streamlining the code. One of those changes was using CurrencyID instead of the Currency name. If you forked it over a year ago you may want to do a code difference check using WinDiff or whatever other application to see the changes.

Just let me know if everything checks out. That way I can close this ticket.

In this case, don't worry. If there was in fact a change from using CurrencyID instead of name, then it's most likely fixed. Sorry for the fuss.

That's a very interesting bug. I made the profession and currency token use the currencyID for each token. It's a unique number associated with each currency. The fact that it's repeated for each localization language is interesting. It shouldn't be doing that. I'll have to take a look.

To be honest, I noticed this with the version I forked one year ago. If you implemented the usage of currencyID within the last year, it might already be fixed. Sorry for not checking more thoroughly.
