I’ve been working in a DYN file.
My brain was nearing a meltdown and I needed a break.
When I came back to Dynamo and opened the saved DYN file…
There are nodes and wires missing.
Completely gone.
What did I do wrong and how do I prevent this in future?
Just me, huh?..well, dang.
@BEN_LEDBETTER You could check if you have a backup here:
%USERPROFILE%\AppData\Roaming\Dynamo\Dynamo Revit\backup
the file would be useful to see.
Looking in the console might yield some errors.
Thanks for the path, sir.
Good to know that’s there.
There was a file, but sadly, it was toasted, too.
Nodes and wires missing…at random?..I’m not sure.
The first two nodes Categories and Get All Elements of Categories were gone.
And then several big chunks in the middle…can’t recall exactly what nodes.
I’m gonna create another file with simple nodes to see if this consistent.
The DYN in question is attached.
WallJoin.dyn (28.8 KB)
It should be mentioned that this was made in Dynamo 2.0 and not everybody will be able to open it. 
Here’s another file.
BecauseRevit.dyn (12.5 KB)
Just simple operator nodes.
This image is before I closed the file.
This image is upon re-opening the file.
Nodes gone…wires gone…pulls out hair
Pretty frustrating.
@BEN_LEDBETTER please look in your console for errors (dynamo console bottom of window) there is a menu item for opening it.
I can open your graph fine, so it seems like an install or system issue.
Here’s what I see in the console at bottom.

@BEN_LEDBETTER please share the console contents after attempting to open one of these broken graphs.
This is what I see immediately upon opening.
I haven’t touched anything else.

Is this the Revit.Categories dropdown node or from a package?
For some reason these nodes are failing to be loaded. Have you tried removing all packages and looking at the notifications menu item?
Would you mind uploading this specific graph, which you just provided the log for?
Join.Geometry.dyf?
The graph appears fine - the revit nodes within it are not being loaded correctly for some reason. (the graph itself is not corrupted so your data is not lost).
Please try the steps advised above.
Was the definition created in 2.0? I have had issues when upgrading definitions from 1.3 to 2.0.
and me
Has this issue been resolved. I am having exactly the same problem.
same here. do you guys also have pyrevit installed? for me uninstalling that helped.
I have the same problem. Graph is missing most of the nodes when I opened a file while it’s perfect on a different machine.
I do have PyRevit, I would rather not uninstall as then I have to get admin involved and it’s a chore getting it again…
