Kevin,

I do not necessarily have the skills to help but are you using vanila node 
and what platform? presumably a linux flavor.

   - Could you have the same wiki open in more than one window/tab/browser? 
   so latest tiddler save wins?
   - The Bob versions help combat multi-access issues, bob.exe is very easy 
   to use (but may be awaiting 5.1.20)
   - If you have a link to such wikis you may consider using a link that 
   includes the target=wikname so that every time you click on the link it 
   opens in the save window/tab, presumably you have autosave to immediately 
   save changes?

In some single file wikis, I have not looked at on node yet, you could use 
5.1.20's local storage plugin to save changes locally, pending the wiki 
save.

Regards
Tony
