Lifts dont show up in cooked map (ut4)

i use Content-RestrictedAssets-Blueprints-Lift Generic_Lift.uasset
with
Content-RestrictedAssets-Blueprints-Lift-Meshes SM_GenericLift.uasset

when i cook and pak the map and play it in XAN-2330705 all the lifts is gone.
I use UTCooker-v0.5
how do i solve this?

U can mark this as solved… think it was that XAN-2330705 is 4.5 and not 4.5.1
it works now in the new public build
