There's a problem in the site.
I check this achievement (I've already get it) but it doesn't stay checked.
After submit it always back unchecked.

I got this before I got access to corrosive weapons. Just kill an enemy buy blowing up one of the green barrels. You find random barrels laying around areas where there are ambushes. Each color has it's own effect.

U can see the achievement and what you've done so far in the menu and u can get corrosive by getting a corrosive gun, a corrosive thing for the bloodwing or blow up corrosive barrels

I'm level 20 and still havent come across a corrosive weapon. I have one corrosive kill because I blasted a green barrel next to a guy. Are corrosive weapons rare? Do they become more abundant later in thte game?
