I ave now succeeded in getting the tilenames and bump values into external files for the EAW.TM2 project.
These files are now read by the exe and the table which contained them has effectively been removed

Naturally, I assumed that this was a problem with my new exe, but I got the same result with the standard exe.
So I think that there are errors in the eaw16.hm file.
