Possible solution for you without clearing the lightmaps.
When I looked in the FPM file I noticed that it does not have the 2 new terrain textures in them,
Try this first. Make a copy of your map for backup.
Open the map and edit the terrain painting, by recalling the path texture you used.
This will generate the 2 new maps needed.
Save the FPM file and reload the map. Try test game now.
If that does not work for you. In my tests I manually cleared the lightmapping from the FPM file, before I edited the terrain pallet texture.
This allowed the test game to run.
Let me know.
Thanks.
