I have a small sandbox wordpress multisite where I create sandbox sites for users of my main installation to test theme and structural changes.

I have a root site (id 1), 3 working as intended sites (ids 2,3,4 respectively) but now whenever I create an additional site instead of making ID 5, it overwrites ID 1. In the database it doesn’t even create the tables for blog ID 5, it just overwrites or adds to the tables for blog ID 1.

The only thing unique about this site versus my other multisites is that we copy sites from proddomain.com to the sandbox.com site via the plugin Snapshot.

Does anyone have any idea what is missing?
