The idea is that any moderator will have rations at every single official mission; all you have to do is come up and ask for one
. I know I've been passing them out like crazy.
As for not being able to report them, most of the confusion is cause by them being hand-written. Try alternate characters if it's giving you an error message; I've come across several instances when what looks like a 2 is actually a Z, or what looks like the letter "I" is a 1 -- and vice-versa on both of these. We'll try to make them clearer in the future, but for now I would suggest emailing or pming me with your specific Ration code, and I'll do my best to get the real code back to you in a reasonable time frame.
For now, I'm going to bed xD
