BC5 aka ATI2 Texture compression problem

[kirill-mapper]

After saving through open iv textures of normal maps with BC5/ATI2 compression type in dictionaries or in models, a reading error occurs and it is impossible to see such textures through CodeWalker, unlike the original vanilla ones, with which everything is fine. Dear developers, could you investigate this error in more detail and check if there is a mistake on the OpenIV side, that after saving the texture, the compression type changes, which is impossible to read in comparison with the original. As an example, you can take for analysis the texture dictionary mapdetail.ytd, which consists entirely of BC5\ATI2 textures. Please note that after resaving the dictionary, some of the internal data changes.
