Indeed, last time I was unable to login to the game properly and came to the forum I had to 'reset' my forum password and I deliberately kept the mail in order to use the same password in future. I copied and pasted that password from the mail when attempting to log in to the forums just now, in order to post this, and it would not accept that password and I ended up having to reset it again.
I do not understand why on earth the forum only login doesn't use the same password as your main login, but having set a new one, at least have the system remember it for future use, please!
As for the problem of not being able to log in to the game, it is annoying as hell to be logged in and playing the game on my Sandycove account and not being able to log in on Northisle because Facebook accounts don't automatically kick you off of logged in status after being idle for some time, but uPlay accounts do!
