I've just edited a part in ST7 sheet metal gone back into the assembly and its been deleted from the model. No facility to undo or anything.
Anyone else seen this strange behaviour. I have MP6 installed too.
I recall there was something a while back along these lines,...but it was related to the "Create Part in-Place" in assembly procedure. Is this what you're seeing?

We also see this.
I've always put it down to graphics card, as usually its when working with very large display sets/and or multiple files open.
Having similar problems here -
My drawing view tracker indicates a file is missing, but I know the location of the file and I can see it in Windows Explorer.
SE can't find it for some reason so is looking in the Project folder (where it doesn't exist)
This is the second such issue in the space of a couple of hours.
I had to use Replace Part last time to point at the correct location.
