Nothing dropping at all

OK, I decided to build a chart for my own interest of what mobs drop what loot.
I started with dune burrowers. I killed 8 of them (well, the same one but i kept going in/out of town).
I got a hammer, a sword, 5 jaws and some gold. Then i got nothing.
I thought that was unfortunate so i killed another.
Again i got nothing, and again and again.

I logged out and tried again, only to get nothing.
I exited the program completely to no avail either.

Maybe it was a glitch with having 5 jaws in my inventory, so i put them in storage and tried again. Still nothing.
Puzzled i decided to kill something else.

I went for the two jade scarabs that thought they could eat me. I got nothing from them either.

I went to elona reach and killed two sand drakes but still got nothing.

And that's where i am now. Can anybody help?

Is it a new (and ridiculous) idea of giving people no loot for killing the same mob several times in succession???!!!

I don't want to jump to conclusions but this doesn't look good, especially from a fun-seeking,pvp hating, pure pve players point of view.
I care little for trade or gold and i only want to hunt for fun and new weapons to better my pve character.
Someone please shed light on this situation.

edit - ok solution found, sorry.
