Urgent issue: Dataflow refuses to save no matter what

[Anonymous]

Hello,

My dataflow since yesterday refuses to save no matter what:

 Sometimes it says that " new version cannot be created because a new version was created when you were editing"

Please help me fix this. I have tried closing down everything and restart PC, etc. but nothing has worked. This dataflow that I have created is gigantic, I do not have enough time to recreate this dataflow

Several similar issues have been reported internally, so stay tuned. Meanwhile, take a look at Dataflows best practices.
