something with instancer

Wherever: pack before instance in copy sop / in UE geometry selector (Houdini Inputs - pack before merging) / or using pack SOP before copy to point sop. Everyhing comes to crushing UE.

HE versions where I faced with: 18.5.633 and 18.5.665
UE4.26.2 and UE4.27 preview 4

there is simple cloner HDA in attachment. If you will try use it on HE v2.0.3 - it will crush. If HE v2.0.1 - works well

add.
HE v2.0.3 + Houdini 18.5.633 + UE5 EA = work well

UE4.27 release + HE 18.5.687
still crush when "pack before instance"

Stable version if HE for UE4.27 is 18.5.532
