Triangle4XP mesh build failure for tile +31-100

[CWattie]

Using a fresh install of the latest code commit, repeated build attempts all result in the same error message (please see below). All other tiles in Texas were able to be built successfully so do not believe it is caused by a limited amount of RAM (see screenshot of tile collection and management UI).

Error message:

Step 2 : Building mesh for tile +31-100 :

-> Modifying curv_tol weight map according to runway locations.
-> Modifying curv_tol weight map according to coastline location.

Looking for bad triangles.

WARNING: Triangle4XP could not achieve the requested quality (min_angle), most probably due to an uncatched OSM error.
It will be tempted now with no angle constraint (i.e. min_angle=0).

ERROR: Triangle4XP really couldn't make it !

If the reason is not due to the limited amount of RAM please
file a bug including the .node and .poly files that you
will find in D:/Ortho Texas\zOrtho4XP_+31-100 .

Did you try selecting road_level=0?
