Card upgrades don't count towards the time to learn of skill already started
I started to learn TR2 (with an initial time of 11 days); I've got some cards, and now my "Skills" page lists TR2 as 6 days to learn, but the progress meter is still 10+ days ...
I don't have other skills to switch to; what else can I do ?
Yesterday someone stopped learning, and unlearned the skill so they could start it again. It did take time off the skill when they restarted it this way.
