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.

I can't provide a full explanation here, especially since this isn't really something I have really noticed myself.

But let me address one thing at least:

All CC3+ maps have a setting that determine if effects are on or off on load, you'll find this in the :CC2RESMODE: dialog. This is a per map setting. If this is off, the map is loaded with effects off, even if it was turned on inside CC3+ previously. You can override this behavior from Tools -> Options

Now, while you experience that effects randomly turns off, I don't know, but i suspect it could be due to loading a file that sets this value. There are lots of cases where CC3+ loads map files, for example, symbol catalogs are actually just map files with a different extension, and drawing tool previews in the symbol catalog window can also be map files. I am suspecting that maybe the value is incorrectly set when something like this is loaded.
