I've discovered a bug that causes ingots (including railcraft's own) to condense into a concrete textured blocks within the metals chest. This occurs whenever the associated metal block is disabled within Railcraft's config.

While this block is labelled as "block of tin: its cannot be converted back into usable tin ingots.

If Railcraft's own tin blocks are disabled it would be valuable if they could condense into the next available tinBlock entry of the ore dict.

Interesting, I think its actually already supposed to fall back to an ore dictionary entry.
