Change Speed: incorrect updating of percentage when "from" speed is changed
Last modified: 2018-08-20 11:51:52 UTC
When "To" speed is set at "n/a", any setting of "from" speed is meaningless, so should not affect the percent change. But as seen in the "steps to reproduce", the percent change may be incorrectly updated.
Fixed in new version of Change Speed effect.
