Pack not working in Lua script

After updated to 2018.0.171, packing from Lua script is not working anymore. All islands are staying in the same position as after cutted (nothing moving at all even when I repeatedly run pack script below).

Here's the pack script:

ZomIslandGroups({Mode="DistributeInTilesByBBox", MergingPolicy=8322})

ZomIslandGroups({Mode="DistributeInTilesEvenly", MergingPolicy=8322, UseTileLocks=true, UseIslandLocks=true})

ZomPack({ProcessTileSelection=false, RecursionDepth=1, RootGroup="RootGroup", Scaling={Mode=2}, Rotate={}, Translate=true, LayoutScalingMode=2})

Full script:

ZomSelect({PrimType="Edge", Select=true, ResetBefore=true, WorkingSetPrimType="Island", ProtectMapName="Protect", FilterIslandVisible=true, Auto={Skeleton={Open=true}, HandleCutter=true, StoreCoordsUVW=true, FlatteningMode=0, FlatteningUnfoldParams={Iterations=1, BorderIntersections=true, TriangleFlips=true}}})

ZomCut({PrimType="Edge"})

ZomLoad({Data={CoordsUVWInternalPath="Mesh.Tmp.AutoSelect.UVW"}})

ZomIslandGroups({Mode="DistributeInTilesByBBox", MergingPolicy=8322})

ZomIslandGroups({Mode="DistributeInTilesEvenly", MergingPolicy=8322, UseTileLocks=true, UseIslandLocks=true})

ZomPack({ProcessTileSelection=false, RecursionDepth=1, RootGroup="RootGroup", Scaling={Mode=2}, Rotate={}, Translate=true, LayoutScalingMode=2})


I've tried to reinstall Rizom, but still encoutering this problem, click pack manually on the UI still working good.
