Apparently there is a machine that, upon given an item and 900 million RF, can quadruple an item.

I have some items for which this is a significant problem (especially given the fact that 900MRF is no longer a massive investment, but instead obtainable 30 minutes into the game with some mods). Is there a way to blacklist some items. If not, could something like that be added?

You can do it in the config, however I'll make it so that you can do it through the API in the next version for you.

Thank you. :)

i would sugest changing this feature to whitelist only as it allows for alot of dupe bugs, an easy example: with the right reactor configuration you can get more then the needed energy from a block of yellorium iirc

Perhaps you right, although that does make it slightly less fun...I'll ask the community

not realy less fun, you could even transform it intro something that takes different amounts of energy depending on the item so other mods could add duplication of there items at a powercost that they see fit, now for example it's the same cost if you double dirt or a diamond block

And then either zero, -1, or Int.MAX for a blacklist. This is a better idea.

...Any blacklist/configurable input system is going to look the same no matter what mod it is from. Wanting to avoid that and doing so by limiting functionality is a very bad idea.

turning a bit to much into equivalent exchange a bit don't want to copy that. Would a white list be okay?

whitelist is the best thign i think, the blacklist would get very extensive otherwise as there are LOTS of things you better not allow duping

But should be configured to opt-out the black/whitelisting system. For players who wants this type of gameplay.
