Why limit the time though? Or why not just force move? Or just don't allow login and force you to convert first.
I transferred my account just fine, but I played at least like once a year. My wife however didn't touch the game for a couple of years and the account is now lost. I did try to convert it once, got an error and decided to do it later, which is my fault but still..
Its a product we paid for, which is still supported and updated. But suddenly is unaccesable because they decided you had to do something to keep acces.. Even when given time I don't understand someone defending this practice..
