Looking through my moderator logs I'm not seeing this- certainly not on every post, I made a couple to test.

Was there any other pattern you noticed to this happening?

To disable the logging in this case go to the Admin CP -> Plugin Manager

Edit the Plugin: Make Global on New Reply [OK]

It's a small plugin, find the line:

       log_moderator_action($threadinfo, '', "Undo Global Thread on New Post");

And comment it out:

       //log_moderator_action($threadinfo, '', "Undo Global Thread on New Post");

There's another log line above this one if you want to comment that out too it's fine.
