When the Stream version first came out, I was really excited, so I logged in to my account on my boyfriend's steam since he already had TFM open on it. I just wanted to see if it was any different. Anyways, when I logged on,it gave him a bunch of achievements through my account right when I logged on. I played for about half an hour after.

After that I logged on to my own steam account, only to realize that I was not getting any achievements. At all. Not even the get one cheese achievement, after like 5 hours of playing.

I think it might have locked my TFM account to his Steam account. Does anybody know how to fix this or is it possible to reset the steam connection?

Hmm... I'm not sure about this since I don't have steam but did you play on the same date or did you go on your the next day?
If you went on next day, maybe wait for sometime and then do all of it
(Don't really refer to this this is just what I think the problem is)

It's been like this ever since the release day. It doesn't seem to be fixing itself.

It hasn't happened to me and i play steam i think your the only one who has this problem

Yes but I don't think you logged in to your account on someone elses steam account so of course you wouldn't have the problem.

I want to know if the mods can reset it or fix it. This shouldn't happen in the first place.

They might of already gotten all of the achievements.

why should it not have happened in the first place? You're saying that the client should somehow know you are not the owner of the steam account? that you have to make a new account for steam and re-earn achievements?

if it has been locked to your bfs account you still consented/chose to log in on it. It's probably to stop some uber account being logged in everywhere to farm achievements or something
