Just like the title says, I add a private pack, such as 152wgt or FTBUnleashed and for some reason, the pack doesnt show up in the launcher unless I add the pack code again. I have to add the pack code each time I open the launcher or I cant play it. Also on top of this, the maps/filter settings button/and texture packs all do not show up untill I add a private pack.
Error log from my launcher.
