I don't have a GMS client, hope someone could provide a sample file to me :>

Only occurs when WzVersionDetection is set to default. image As a workaround you can set it to fast.

The root cause is a little complicated, Wz_Image.TryDetectLuaEnc() method has some side effect, it will overwrite the crypto keys in Wz_Structure level, and finally cause the next Wz loading with a wrong crypto key.

KMS version is not affected. (I've loaded with WzVersionDetection = default)

Reference from https://github.com/KENNYSOFT/WzComparerR2/commit/e21868553f9b6f50044def6a78b7b682f89e2045 Only store encType instead of entire Wz_Crypto for saving memory cost.
