Unfortunately I couldn’t view the changelist number as it was restricted, but I did find this commit by the same person on that day that looks to be similar at: https://github.com/EpicGames/UnrealEngine/commit/cfe3d90e5528f56d5c19f186539899d0d3052fb5
or Commit cfe3d90; Fix potential data loss of changed properties on placed components of a derived blueprint class that does not modify the component
If this commit isn’t what you’re looking for I’ll go ahead and push this case up to Epic so they can provide more information on the fix.
As for correlating changelist numbers to a commit, I don’t think there’s a direct way unless the commit comment contains the CL number.
Thank you!
