Optimize database results in forms that need to be updated

We run an optimize on a regular basis, but everytime we do that 10% of our forms need to be updated. Just saving every one of them is enough, but is is quite annoying & time consuming. We checked that accounts were not changed so it is a mystery? Most of these forms are free forms. Anybody any idea why this happens?

which version of controller are you using? Looks to 8.2 or 8.3 to me… Because in 8.4 (FP1) you can select multiple forms at once to update. This saves some time but is still no solution…

Those 10% of the forms, are these always the same set of forms?

We are using 8.4 and yes it is always the same set of forms. It takes time because if you forget it, users call etc…
