All monsters have multiple movement, but they always only move 1 tile per season (unless they were riding a road). Wolves somehow skips this, and only skips it on the very first turn. Hence the bug report.
Fair enough, just getting through the "troubleshooting" issue, if I cant understand it, little reason the devs can 
Bugs is more easily spotted of you put on a version number ( [0.915] ) and [Bug] in front of the name of the thread, and also puts it in the subcategory "FE Support".
Only telling you so there is a bigger chance to see it fixed
