The attached pic shows 2 terrain .ASC files.

The upper one is the original (an export from buldozder) which was imported into Reforger for terrain editing. As you can see in the header is on 4096x4096.

After doing some terrain editing within i exported the backed data back into a new .asc file (bottom half of pic).

Problem on the new exported file: Now the header changed into 4097x4097 and the first data line seems to be duplicated.

Problem: This file cant be used now in other programs as a reference of the original one (since it differs from the original one).
