Hello guys,
we have noticed another strange behaviour when saving objects (tables).
This may be related to our new update (Build 30712).
I have had this problem with three tables on different days.
If I have saved a change in one of the three tables, the following error message appears:

To finally be able to save the table, it helped to restart the services on the table via the Adminstration Tool. Then saving was suddenly possible.
Thank you very much.
