Long time no see, long time no suuport. It was about more than month I 'disappeared'.
I don't want go to details but simply I personal life didn't allow me to work on OC.
That's about to change and I and hopefully Usagi and others will continue developing, supporting and growing this awesome project and community!
So, the first I screwed up was vmaps4 (issue #1133). Although I spent enough time for testing the new vmaps I tested only new stuff not the old, I really didn't expect that geometry calculation could go bad.
But now vmap_extractor is fixed and to minimize your update time, I have uploaded both vmaps and mmaps. They are ready to be used. Enjoy.
