On Friday afternoon I spent about 30 mins doing drawing edits.
I had to undo a single line placement and it instead undid everything since I opened the file.
I tried clicking redo and it all came back....
I thought this really odd, so I saved the file and closed it.
I re-opened it to test and 'undo' appeared to work as normal, ie the undo button would only undo one step at a time.
I continued working for another 30mins, went to undo something, and again, it undid everything for the last 30mins, only this time it crashed in the process. When I re-opened the file I'd lost 30mins of work.
I understand there is now an option to "set a mark" in the undo tool - however I have not used this.
I have also been using the undo tool from the "standard" toolbox menu, not the ribbon menu.
This is not normal behaviour obviously.
The undo tool in both places issues the 'undo' command, as does 'Ctrl + Z'.
Has this occurred with just one file or have you seen it with other files?
I suggest compressing the file before starting work on it, select all options.
OBD saves every time it spots a (very) brief pause in user activity.
As you work are you seeing the save icon (floppy disk) persisting? It should disappear as soon as you pause:

Happened again to another drafter in our office - different model.
He said it undid everything since he opened the model.
He was able to click redo and it all came back.
Yes the floppy icon appears regularly.
The icon will appear as you work, as long as is disappears as soon as you pause it will be indicating normal operation. If it stays visible for a noticeable period that could suggest latency between your machine and the file location. Are you home working and how are you connected to your files?
Did/does compressing files make any difference?
How big are your files (just for information, could be relevant to thinking about network latency)?
