NetBox Version

v4.4.5

Python Version

3.12

Steps to Reproduce

1. Create a device
2. Create a virtual chassis, selecting the device as a member
3. Inspect the device's changelog
4. Edit the virtual chassis
5. Remove the device from the members list
6. Inspect the device's changelog again

Expected Behavior

At steps 3 and 6, the update record should show both the pre- and post-change attributes of the device.

Observed Behavior

The post-change data in the changelog entries is accurate, however there is no pre-change data present in either record. Instead, we see a warning message:

Warning: Comparing non-atomic change to previous change record
