Sadly i am experiencing major bugs when using the gumball in the wip atm.
The Bug regarding missplaced gumballs when copying objects luckily already was fixed - now i am facing a mildly (very) frustrating one:
Resetting the Gumball does not work when handling grouped objects - for single objects everything works fine - don’t know how to offer more insightful information 
The workaround i have is ungrouping and grouping again to get a reset gumbal.
Cheers and have a great weekend!

Edit:
Undoing (strg z) usually resets the gumbal (very annoying as well) - but not even that resets the gumbal for groups atm
//please keep that though :b
PS: undoing (strg+z) resets the gumball position - imo it would be very beneficial to have it stay at the previously set position
PPS: anyone reading this? 
I think you could post an example with some geometry and maybe for developers it would also be interesting which build you’re using…
