Thank you for the detailed report! 👍.

Is this issue constant, or just happens occasionally?

The logs suggest that it is throwing null when attempting to get the number of files in the config directory, however, I can not reproduce the error in a test environment.

Off topic note:
You probably don't want clientmods in the directory include list. With push client mods on this will most likely sync that directory twice. Once as client only mods and once as normal mods.

Closing as this has had no traction.
