I am pretty confused by this and looking for any insight into what could cause this issue.

I have a user who has been in our system for about 20 weeks now who has recently started spamming people with emails. The same email saying the diff has been updated / created is being sent over and over (about 20 times so far). This has translated to about 600 emails being sent so far.

The strange thing is that although I can see in the users profile that this is happening on the actually diff it says it's updating no new transactions are being created in the timeline. I did check all the transactions in the database and all seem normal to me. I only see one of each and don't see any funny timestamps or value for the new or old value.

To summarize this question how can transactions appear on a users timeline but not on the corresponding object that they are updating?

EDIT:

The only notable thing about this diff is it has a large binary file in it.
