When packaging, it looks like there’s a problem in rawmesh.cpp in the serialization code where it tries to allocate an array of 0xcdcdcdcd length. I’m having the problem with many objects, but Content/Env/Infil1_City_Decos/Material/M_Infil1_City_FingerBracket_2.uasset triggers it for me, for certain. I have a call stack if you care to look at it. All I can do for now is delete the offending uassets and rebuild to get a little farther.
