Trackpad scrolling stops working when Magic Mouse connection lost

Describe the bug
When bluetooth connection to the Magic Mouse is lost (ie. when mouse is turned off without explicitly disconnecting it through bluetooth menu) the MacBook trackpad will not respond to two finger scrolling.
I can move the cursor, and the two fingers touching the trackpad is registered (evident by window scrollbars appearing), but no scrolling happening.
Fixed by restarting BTT or reconnecting the magic mouse.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
MacBook pro Trackpad / Magic Mouse.

Device information:

  • Type of Mac: MacBook Pro 13", early 2011
  • macOS version: macOS High Sierra, 10.13.6
  • BetterTouchTool version: 3.086 (also happened in earlier versions, don't remember the version number, but with the old layout)

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):
I only have triggers for the trackpad (4 finger click) and magic mouse (3 finger click, 3 finger swipe up/down).

+1, I have this issue too. Manually restarting BTT fixes the issue.
