I am posting this to report a major bug in FSX Build R26. I have been working on the Springfield/Branson Airport (KSGF) from stock and modifying it by changing all taxiways to concrete and adding gates. I came upon the bug when I was noticing that every time I saved it took longer and longer each time. I soon realized that for some reason my XML file gotten to over 10 MB in size when it should be alot smaller.
The next thing I did was checked to see what was going on with my XML file and I was noticing it was duplicating all the scenery each time I saved. So basically every time I saved my airport it was doubling in size each time, without my knowledge.
I did find my own way of fixing problem and getting the file back to its proper size. Doing this involved:
1. Saving the airport (yea it will take time becasue of the bug)
2. Closing the airport in FSX Planer
3. Reopening the same Airport.
4. Saving the airport again this time using the "Save As" function.
For now I would recommend this until this bug is fixed hopefully in the next version. I would love to be able to attach the buggy airport but my quota doesn't allow files of more than 1 MB.
