- Changed FStateTreeHandle to FStateTreeStateHandle, used only for indexing states - Added uint16 and uin8 index types, which can represent invalid index (aka INDEX_NONE) - Changed indices that can be optional to the index types above - Added validation and error loggic when index types overflow during compile - Removed 2 indirections (in common case) and halved the memory usage of property copies #jira none #rb Mieszko.Zielinski #preflight 6295d26e91004dd61ced370b [CL 20434838 by mikko mononen in ue5-main branch]
