Password is correct but says wrong password (Reddit)

[Thresh]

So whenever I try to log in to Reddit with LastPass, it says "Wrong Password".

The fields are already populated by LastPass, but says "wrong password".
I click the number symbol in the user/pass field and select the correct LastPass entry, still says "wrong password".
I click the number symbol in the user/pass field and COPY the password its showing me and PASTE it into the password field - what do you know, it works!!!

I've removed the content from the boxes so when I populate it with LastPass, I know its actually filling the boxes.
I've updated LastPass to some gibberish password and then back to the correct one, but it doesn't solve anything.

I have a second Reddit account, and it logs in fine using the LastPass populating feature...

The only thing I can think of that is causing problems here, is my account with this issue has Reddits 2 factor authentication enabled??

Just enabled 2FA on mine and logged out and it and it was fine, but to troubleshoot try disabling 2FA and rebooting, what happens then?
Also clear browser history and cookies and restart, any change?
What happens if you use different browsers? specifically Chrome AND Firefox?

I just cleared cache and no luck.

I just thought though, i'll try on normal www.reddit.com and it works, but on the www.old.reddit.com I use (for the old style), this is where the issue explained above happens.
