Loading & unloading Data Layers several times will lead to missing collision of whole landscape. Happens only in packaged build, happens 100% times. Sorry, I thought I replied to their post… Removing the Data Layers from the engine fixed it. Window → WorldPartition → Data Layers Remove all data layers in that window and actually delete them from the content browser. Save + Compile + Package Game, then test.
