Gooseboy

so ive been playing on a lan sever with my boyfriend on a mod pack, then we played another mod pack together on another lan server and when i joined that one i was an alex skin, no big deal whatever maybe its that mod pack. well we tried going back to our original modpack we were playing and it completely started me over, alex skin, at spawn no inventory. the only thing it saved was my saved crafting recipes on the tmi mod. any help?
