.ESP Patch bloating from 3MB to 24MB - file corrupted?

[plutocene]

I have encountered an issue while making my navmesh patch. I add a single small navmesh to the patch, and suddenly the file size goes from 3 to 24 MB. I went back several hours and recreated the patch and it still happens. I can't find any data that shouldn't be there, there are no errors in Xedit. I can't explain whats going on. 

 

Ideas please?

 

Edit: I started using a temporary patch file for working and then copy the entries into the main file in Xedit. No more file bloat, speeds up process.

 

Edit 2: Definetly something broke with the file while editing it. CTD on start-up with the updated patch, even though no errors visible. Can't explain it, will go back to working version, perhaps someone can shed some light on this.
