On the new Minecraft launcher the Skins servers and realms don't work for me so when I try to join a server it says ( Internal Exception: java.lang.NullPointerException ) and when I try to join realms it says ( Invalid session Please try restarting Minecraft ) and the skins are gone for me I try getting the skin I press change and then I get on Minecraft and I don't have my skin! Please, Mojang fix all 3 of these! I am almost not able to do ANYTHING on Minecraft besides play 1 player worlds
