When I upload to Google Drive, I zip the whole file set and put a serialised version number as part of the filename. (rising in units of 5) before uploading.
Eg. war_plan_red_orange-15.zip
Then there is no problem of filenames changing.

Dont leave the zip in the downloads folder as when TripleA runs it will unzip and might over write any changes you have done.

@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...
