Rare skill training issue resolved (http://community.eveonline.com/news/news-channels/eve-online-news/rare-issue-with-skill-training-has-been-fixed/)

We would like to inform you that we have resolved a rare issue with skill training. This fix went live on Tuesday, July 25th 2017.
Some pilots who had skills queued up in their skill training queue (https://support.eveonline.com/hc/en-us/articles/203217062-Skills-and-Skill-Queue) could have - in rare circumstances - been affected by an overly long training time on their last skill in the training queue if their subscription status changed for a short amount of time.
Currently, we are compiling a list of the affected pilots and will compensate them accordingly. There is no action required on your part: you will receive compensation automatically in a future patch if you were amongst the few affected pilots.
