So... I can't imagine that this hasn't been mentioned... But... Have you considered adding modules to protect against various negative effects, such as nausea, poison, or withering?
I have the same problem. Can't get it to work properly. I PM'd the creator.
Cool... unfortunately he's not exactly around much anymore, apparently he's got some other stuff he's working on, and of course i'm sure he has a life. Been a problem for like 3 versions now lol... hopefully it will get fixed in the next couple releases. not totally game breaking but makes it dang hard to use, even though i really only use it for nuclear containment fields at the moment.
For anyone that's interested in the problem, I have the recipe bug, where the crafting recipes for any of the MFFS items, including the cards, will not work. It is worthy of note that if you cheat the items in to the game using NEI, the items do function correctly -- you simply can't craft them. Furthermore, if you stick NEI into recipe mode and try to look at the recipe's for anything MFFS related, it can't show a recipe -- it's as if they don't exist. I haven't had any problems with java or other minecraft errors.
Furthermore, I created an instance of minecraft where the only mods i had installed were ic2 1.95b and it's prerequisites, Modloader 1.2.5 and Forge 22.214.171.124, as well as MFFS itself, used all the default everything (block id's and such) and had the same problem -- no crafting recipe's work. I did have NEI installed as well on this instance, but unless code chicken core or NEI themselves are somehow causing the problem.... And even then after i cheated in the items needed to craft an MFFS item (to test to see if i had the same problem), i went and uninstalled NEI and code chicken core, and then reloaded this test world and tried it and the recipe still does not work. Anybody?
