So I am putting together mods for a server and most of everything works except for two mods, ZAWA and age of weapons. The mods work perfectly fine in singleplayer with every other mod I have been using but when I go into the server they have tabs in the creative menu but they are blank. I have checked the console for any errors but nothing including the two mods, so I have no idea why or how they are breaking. Does anyone have any idea what could be causing this? Or a fix?
