(#2674) - Fixed "writing past the end of the buffer" error when calling ResetDirty() on managed network variables that are larger than 256 bytes when serialized. (#2670) +- Fixed issue where generation of the `DefaultNetworkPrefabs` asset was not enabled by default. (#2662) +- Fixed issue where the `GlobalObjectIdHash` value could be updated but the asset not marked as dirty. (#2662) +- Fixed issue where the `GlobalObjectIdHash` value of a (network) prefab asset could be assigned an incorrect value when editing the prefab in a temporary scene. (#2662) +- Fixed issue where the `GlobalObjectIdHash` value generated after creating a (network) prefab from an object constructed within the scene would not be the correct final value in a stand alone build.
