So basically I'm glitching really badly right now on this factions server. I have no clue what to do apart from just deleting the .minecraft folder and seeing if that works. But will that make me lose all my stuff on the server?
.minecraft folder will delete your single-player worlds, resource packs, mods etc.
Deleting this folder will NOT delete anything you have on the server, since the server files are not located in your
.minecraft folder, they will be located at where the server is being hosted.
I am assuming this server isn't a local LAN server that you are hosting, where deleting the
.minecraft folder could delete your world.
Ok! If you delete
.minecraft you will NOT lose the stuff on the factions server (trust me) (it is the server owners that have all your info) (not your computer) BUT when you delete it, don't delete your
saves folder and
servers.dat (this just tells Minecraft what servers your have in the multiplayer list) Once you do this, re download Minecraft! It should all be fixed! IF NOT contact the server owers
