ScottHope:
Is it a mouse issue, low battery, broken cable, dodgy button, poor USB connection?
That was my first thought as well, except funny it would only be happening on putts. One would think if the mouse just happened to go bad around the same time as an Update it would effect all shots?
Maybe @Squatch should try a full uninstall/re-install? Discord is usually all over this stuff, and no one on there seems to be complaining of the same issue so seems to be limited to Squatch's hardware or a glitchy update.
