Very short notice and then nobody could make any withdrawals at all. After the project talked to the OL guys they agreed to extend the window a few days but everyone had to pay a 10% fee for withdrawals because they had to be done 'manually'
From my understanding a good chunk of the coins belonging to less active holders are still in their hands, and may likely remain so
