Issue:
Get error preparing checkout.trn file on Toolset - "The model may have been corrupted. Do you still want to save it?"

Customer selected 'OK' and the model appears to be working and correct.  Is it ok to continue or is the model corrupted?
Resolution:
Yes, users can select 'Save' and continuing to use the model, it is not corrupted.  

In Gen 8.5 a PTF (TSN85028) was created to change the messaging,
From:
"Memory corruption in model, cannot complete request." and users could not save the mode.

To: 
"The model may have been corrupted. Do you still want to save it?"  with the option for users to save the model. 

Additional information:
Users are OK to proceed with the save on the model. This is not an actual corruption, it’s a memory error reported by the memory validation process. The code reports it as if it’s a memory error, but once you do select the save, it has no problem creating the memory structures behind the scenes and proceeding with the save.
