I'm not sure if this is a bug or not but I got a fatal error message while trying to load Xiangqi UCI engine from the "Engine" menu. The error message"Variant xiangqi not supported by ggchess-uci-x64-u820091"
The engine works fine if I mannually update first engine section in xq.ini
"UCI2WB ggchess1124.exe C:\WinBoard-4.6.0\engines"
