Ahm yeah, in the INSTALL_DIR it is in the s3tbx directory. You’re right.
That it now works is not good news. But I expected it. This means that modules updates are not considered by snappy. Or at least not correct. It might be random from run to run which module is used. Either the old 5.0 module or the latest module e.g. 5.0.7. This means snappy is not reliable.
I consider this as critical issue for the next release.
