I am running the latest version of this module and I see this exception quite a bit using this module in my API:

The create method may not be called on a loaded entity. Use the update() method to update an existing entity or reset the entity state

It comes from ActiveEntity.cfc line 128.

But I am calling it using this code:

getModel('LoggingService@MYAPI').reset().populate(prc.apiLogEntry).create();

which IS resetting first, as instructed. I have not found a pattern when this happens -- it doesn't happen all the time. Any ideas?
