1) That is IC2 missing NEI support, so really not my stuff.
2) that they have now 4309:1 when crafting is correct. The 4309 are wrong.
3) Jep, really missed that one recipe. Fixed for the next version.
4) As i wrote, 4309:1 is correct, so it working is also just right. Also found that 3 10k cells into 1 30k cell does not work, but that is a IC2 recipe i do not touch, so IC2 bug.
That all broken recipes, or are there more?
If you're collecting broken recipes, I found that in 3.1.14, the thick neutron reflector isn't craftable (uses a beryllium plate surrounded by four neutron reflectors, I think).
