@wc_sumpton THANK YOU. Checked for that vary thing, but stepped through using the Linux ImageViewer and it skips bad files. Strange it existed because the imageTiler was run a few times after first encounter with the error. I'll check the rest.

Observer error be gone. Uploaded a new neanderthal.zip. Wrapping display conflict still exists. Each loop in a polygons.txt territory definition should get its own display bounding box to determine if it is in the view.

I'm going to concentrate on the game development. Once done, I'll clean up the scripts for public consumption.

@TheDog Thanks much! I did try file associating .properties files with Notepad++ before, but it's still always uploading the file as a text file instead of a properties file... any other ideas? Google is being no help.

@GREGOREK

Check the baseTiles 7-17.png is bad. This is causing your problems.

Cheers...

I'm still hunting down the Observer-Null error, but higher forces need to get involved on this one.

Turning wrapX and wrapY off, the cell boundary display error is gone.

Turning wrapX on, the cells display properly but the small map drops the right edge.

Turning wrapY on, the cells get truncated and the small image drops the bottom edge.

The game provides 'island groups' in the polygons.txt display but was never tested for map border-crossings, wherein a territory can exist on opposite sides of the map and a single territory can exist at all four corners. It looks like a bounding-box oversight. For complete wrapXandY this needs to be addressed on the engine side.
