AutoCAD Inventor :: Saving And Checking In IAMs

I have Machine.iam with all children checked out, except for company-library-parts and Content Centre parts.

After changes to non library parts and checking in machine.iam (with 1 or more company librarie .iams in it) Inventor says: machine.iam and (x) dependent files must be saved.before they can be checked in.save and continue?

Answering Yes -> Inventor says: One or more documents have been modified but save was unsuccessful. You must save the document prior to check in. (but I did save before check in!).  Only option is to press cancel..

All filenames of library.iams in the vaultlist in inventor are turned red with an * behind the filename stating they have changed.(?) Somehow inventor thinks the library.iam haved changed in this machine.iam..

If i do this again with all included children checked out, but not the library files, the result is the same.

I tried to find out what is wrong with these library-parts (all library.iams (?)) so I opened a few of these library.iam (with the librarie.ipj) and the update button is greyed out so there are no changes..

We “solve” this now by closing the machine.iam, inventor then asks: save changes?, press Yes, an new window pops up: file “machine.iam” is checked out to you. Do you want to check it in now?, press Yes, a new window pops up asking which files you want to check in: machine.iam and all checked out parts in it, press OK and all will be checked in.

But this only works with files that are already in the vault, not with new drawings of iams.

We used to have the problem after saving an part or assembly -> Inventor would ask after pressing close: do you want to save, as if the first save didn’t work.. Now we have a bigger problem..

Also sometimes checking out include children only includes all direct children and not also children of children.
