Ah, excellent! I can confirm that the new build seems to work! Thank you very much! 
I have a few new problems to deal with, but none for this thread, I think.
One is a combination of my own code and Deploy-ng’s egg-renaming: I have code that checks for model-file existence, and which assumes that files are either named + “.egg” or + “.bam”–I didn’t account for + “.egg.bam”. So I’m going to go through the various places in which I’ve done this and correct that, I think.
The other seems to be a bug, either in mouse-cursors or DirectGUI–but I’ll open up a bug-report on GitHub for that, I think…
So, for now I seem to have Deploy-ng working, and builds being successfully made! Thank you for all the help, rdb and Moguri–it’s much appreciated!
