it happens several times on different machines with beta20… when i change the count of a group(ex9) inside the inspector, it turns into a “loop”. that means that v4 creates a endless count of slices until dead.

i assume when changing the input count by right-clicl-n-drag?

i also noticed ugly problems with mouse glitches on ALL nodes with “pin count”-pin (stallone, + , …).
workaround: doubleclick and type desired input count.
