I'll dub it the V bug. Tapping the Move shortcut v and then tapping another tool like the Lasso shortcut--L, causes the Polygonal Lasso tool to default to the regular Lasso Tool.
The same goes for the Wand--w and the Crop--c Tool.
It seems the V shortcut triggers this behavior in 2017.1.0
This bug cannot be duplicated in Photoshop CC 2015.5.2
Details here: OSX
And odd enough, even one for Windows 10
