Post count change?

[Roughneck53]

Hello, my ‘Post’ number has reset/bumped lower by approximately 350 posts. Yesterday I was at 668 posts and today I am at 285. I have been an active member since December 2016 and this is the 2nd time this has happened. Two years ago or so it dropped from 500 something to 285 also. Not sure what’s going on??
Please reply in case I am doing something wrong. Thanks, David
