I think that's because those images are using the wrong relative reference. They are using the #-reference, which means the CC3+ installation directory, instead of the @-reference which means the CC3+ data directory.

Try running the FFIX command first before running my command again.

If you need to know exactly what is from which add-on, you can use the IRD command (D stands for Detail).

And that cobble fill is some weird reference that turns up in some templates.

Ah, yea, you need a newer build of the dll file too.

I've uploaded an updated zip with a new dll file too. Remember to close all instances of CC3+ before replacing it.

I wrote a tool for that: http://cc.monsen.cc/tools/cc3monsentools.html

Yea, that's DELAYDRAWSYM.

That setting is system-specific and not map-specific, so it won't be automatically turned on when people load the map unless is it is added to the map loading macro.
