Thank you for contacting us with this issue.
Bruce, also we got your bug report and we can see that you are using the Bloom R11 version of the IDE.
So this tells us that the issue is not related to the recently implemented support for managed packages, and this for sure is not related to the issue when you don't see local tests from your remote organization during the deployment to another org.
May I please ask you to check if the issue is reproduced when you use the 'Deploy objects' functionality instead of the 'Save&Deploy' button. For this, please make any changes in the same object file, open the menu Project and select the 'Deploy objects' item.
If you would get an error, please share it with us and, in addition, you can also send us a bug report with the attached log file directly from the IDE after this.
Also, can you please tell me which types of fields are present in your 'Contact' object? This will help us greatly to understand what exactly can cause the error.
One more question: is the issue reproduced for all your objects (standard and custom ones) or for some of them?
We would greatly appreciate your help!
