From time to time I get this warning regarding “Warning: Terrain: Clamping Offset nn to nn.”:

The only post about this I could find says by setting TERRAIN_OFS_MAX=0 this message can be eliminated. (my current setting is 15)

I don’t want to message eliminated - I want to find out what’s causing the warning, so I can correct it.

Can someone please help me discover what’s causing this warning to occur?
