i was wondering if anybody on this website knows how to fix the invalid session problem you get when trying to connect to an 1.7.2 minecraft server. The reason i need a fix for is that i play on grifeing and raid server with my friends before that fucking problem started with the invalid session Fecal Leaking.
im pretty sure this was a server side issue if it isnt try deleting ur .minecraft and redownloading using the default mc launcher
Try installing a cracked version of minecraft and check premium mode and sigh in and check if it works like that
