But why are you saving the whole scene and using the Team Render Server web application? For me, it looks easier to turn your Team Render Server to ordinary Team Render Client and simply use the "Team Render to Picture Viewer" (when the bug with unfinished jobs will be fixed). You can also use your main machine as the client by enabling "Edit -> Preferences -> Renderer -> Team Render -> Share Machine over Network".
Great I'm glad you were able to reproduce the problem and I hope it is an easy fix for you.
For our studio the web app is much better. We have multiple people sending multiple jobs. When a project is ready to render I have a little script that collets all assets saves them to the admin folder and I just need to press start in the web app and keep working. My machine is not affected and the farm just renders our jobs. This works great to queue up both still frames and animations and all users can view progress, quite jobs, change priority, delete jobs, get there final renderings etc. Much more seamless and effective.
I might use it the way you suggested if I was the only person rendering or if I have an urgent rendering that needs the combined power of the whole render farm.
