Well, I donated 250 ingots for 'science'. I didn't really expect anything great to come out of it - the whole thing smelled very much of some 'maniac' doing 'scientific research'.However, after the bar filled up completely (which in and of itself took ages - especially with no change in the required mats), absolutely nothing happened. Our mad scientist just continued collecting mithril. I waited for maybe 5 more collections after the bar was full, but as still nothing happened, I decided it was probably bugged and left for something more fun.I didn't expect any great reward, but no outcome at all (not even 5000 Karma or some kind of funny mystic forge animation or whatever) was definitely underwhelming. I hope it gets fixed so even those of us who decided not to keep looking at a pretty boring bug can experience what was meant to happen.
