So I was doing some testing today and well... I noticed something that breaks the progression this mod adds to Tinkers' Construct....

Once you get iron you can just go get some lava and water and put it into the smeltery to get molten obsidian, then you just add some aluminum and iron and you just skipped 2 mining levels. unless i am missing something in the config to disable the obsidian smeltery recipe.

I'm using TConstruct 1.8.1 and Iguana Tinker Tweaks 2.1.0.

i hope this issue hasn't be solved already, i looked around for a previous report on this. If this is intended then that just completely breaks the point of this mod in its default configuration.

sorry if this is an erroneous report but i figured better to make you aware of the issue.

You are correct. I think the old one even had something like that. Will be in the next version.
