Yes, because playing GT is relevant to this discussion how?
Saying FML has a bug when you're using it and it's not working as you want can only be actually defined as a bug if A) FML is documented to work as you intend and isn't, or B) You wrote FML. Otherwise it's a feature you want, but doesn't exist. Hacking it in...well, that's just unethical in my book.
As I also said in TiC, I'm not against Gregtech...I'm against Greg's implementation of it.
