Heads up concerning the issue date in the title block. I'm getting very erratic results when publishing; sometimes the title block drawing (on the master layout) updates automatically, sometimes it doesn't. If that drawing doesn't update, your title block data will be wrong, including the date.
I have confirmed that the drawings on the master layouts are set to auto update. That should be all it takes, but it's not.
For example, I changed the date and then published a PDF. The dates on the resulting PDF sheets are not changed. I immediately published again, without making any changes anywhere in the project. Now the title block is right.
The title block drawing will always update if you open its master layout. It seems it will also update if you open a regular layout. But I have seen cases where the layouts of some masters are updated but not others; it probably depends on what regular layouts have been opened.
But, each layout automatically opens as the publication happens! Yes, and it skips updating the master drawings. Sometimes.
Once again, we have an output-related, liability-hazardous, supposedly-automatic behavior where Archicad can't quite get the door all the way shut. And once again we have to follow it around making sure it's using its litter box.
My recommendation: If you are publishing anything where the date is critical (that's anything you're giving to anyone else), before publishing, open each master layout that is in use. Essentially, that's all the masters of a given size, just to be safe. Opening the master should trigger the auto update of the title block drawing, and then you should be set.
