Cant sub to newsletter, token is invalid

[RafaMonteiro]

Trying to sub to Surviving Mars newsletter but when I open the confimation email it says the token is invalid and puts me back at login.

I was already sub to the paradox newsletter and appears that Surviving Mars cancel my sub to it and now I cant sub in neither of the two.

Sounds like a major bug.

Edit: Now even if I request a new sub from the paradox 'main' newsletter I get the same invalid token message.

I have fix it on my own.
The link that comes with the email is: sandbox-account.paradoxplaza.com/confirm

Delete the 'sandbox-' part and it will confirm.
