I recently came across an OAR file import export issue and would be happy if anyone of you could try to repeat this issue.I took a couple of months old OAR file which was of file size X, imported it and then exported it immediately today. The new resulting OAR file is now of file size Y, which is about 10 MB larger than X.
This difference in OAR file sizes even if nothing has been done in the world it generates warrants further investigation.
Let me know if others observe a similar occurrence.
1. Find an old OAR back up a month or two old.
2. Import the file
3. Log into the world
4. Export the world again to create another OAR file
5. Compare file sizes.
