So me and my friend started playing the game lan on his place yday. Today i installed TL2 on my house but my char isnt there. Is he stored on my friends hard drive somewhere or i have to go play him on internet so i can "download" him on my pc? Weird...

C:\Users\xxx\Documents\My Games\Runic Games\Torchlight 2\save

this is correct, you'll need a flash drive to transfer the folder over

or zip and upload to zippyshare or something, save is only a few MB.

yea, could use team viewer aswell or logmein

Thanks this worked. But before that i tried to sync with cloud. Did that on my friends pc, got back to my place and my char wasn't there again. I hate the fact that i have to use my flash drive and carry my char around all the time.

If you setup a small FTP server between each computer you could copy and dump each time you're done playing. You could probably find a cloud program that will sync the specific folders contents every hour/on demand.

Shouldnt all these happen automatically? This thing annoys me

It should if you're logging in with your account, I agree.
