just remember people - there are a lot of 3rd party modules for cartographer .. as such problems with those modules need to be directed at the authors... and for lack of a better place this thread would be a good spot.. :D
While I agree, that the Cart plugins that I'm so dependent on were written by other authors, some form of notification must be made to them, as Cart is now basically useless since none of the plugins work at this point. All 18 or so of my plugins return errors on load directly referencing the new RockLib etc.
Hopefull this can all be straightened out soon in order to get things back to normal and working together. I'm highly dependent on my addons, and this is a bit ridiculous.
Good luck, and try to stay sane because this may take awhile to get everybody on the same page, and working together.
