I've been going over the drop tables, there's some tweaking needed. Thanks for the feedback!
The res-issue is not something new. It's been around for a while, but we thought to have fixed it a long time ago. Perhaps it was 'unfixed' with something in the update, we'll have to look, however from all our efforts, we cannot seem to reproduce it... yet. We'll keep trying. The more details you can give us regarding what's involved, the better we can try to reproduce the error.
The ammunition thing is confirmed and we're trying to determine why and fix the issue.
Thanks Leo I also found my lvl230 champ got ALOT of drops in dod from boss type monsters (white) as apposed to scorpions and mini devourers who are much more level appropriate and dropped 1 thing if I was lucky
