Zacade found a fix for the issue that !zclass and Chat color settings would reset for many players. It should probably not occur any longer that your settings reset after map change or after that you disconnect. Also if you connect today for the first time your settings are reset because except of the fix we also cleared out our sqlite files for client prefferences. Currently the fix for prefferences is only active on ZE and ZH. if ZR or MG will need it we upload them there too.
