I want to research "Advanced Iron casting 2", but it is still marked as red (prerequisit not researched yet), but nothing is shown as missing in the UI. When i had a look into the sourcecode i noticed, that it has prerequisites to Bob's mods technologies, that are disabled later on. It seems like only the technology is disabled, but the prerequisites are not.
We were able research "Advanced Steel casting 2" and "Advanced Copper casting 2" without any problems.
How can we unlock that technology? And if that is a bug, please fix it for the next release
