Hmm nothing I can do at the moment, I've tried all kinds of possibilites but the blocks simply get orphaned .. Not rejected, not errors whatsoever, they get mined fine and after the next block they're orphaned. I've compared transactions, blocks, nonces etc.. all is good, i've tried z-nomp as well with no luck..

I'll give it up for now, without any error message it's hard to debug as well.
