FBW A320NX Custom Violent Pitching

I’ve just restored a Custom version from last week (27th) from a backup, and I have just repeated my flight from LFPG to EGCC, and it worked perfectly without any violent pitching! The whole flight and the AutoLand was as smooth as silk!

The build I am on according to the installer is: a56c2ed, unless that is the latest one waiting for me to download and update!
Is there a .cfg file with the relevant build info in that i could let you know about?
