Design file changed in drawing space

[s.mckenzie.fugro]

I was just about to start the last page of my fusion drawing but when I went to add the base view the reference model had changed somehow. Any ideas how it could have happened & how to change it back to the original model.

You have not given enough information.  Please attach your model, a picture or video of the problem.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

I have been creating a drawing in fusion from an existing model & every other page was ok till the last one when I looked to add a base view it was taking in a different base file as seen in screengrab 2. However when I create a new drawing using the same model as per screengrab 1 its fine.
