On a server when I try to add coal dust to the manufactory, the server crashes with the error below. I do not have IC2 installed (last version it worked fine without it). I understand that you removed prepacking the IC2 API with NuclearCraft but I strongly suggest you either include it OR properly make it an optional dependency as there is no real reason that IC2 should be a hard dependency.

NuclearCraft-2.10c--1.12.2

That also happens to me too

Sorry, my bad. IC2 should be a soft dependency, but I just forgot to check if IC2 was installed on that particular method - will get a fix out right now.

Thank you for your quick response, I will let you know if I run into any other errors where it is trying to use the IC2 API without it being loaded.

No prob - I was reasonably thourough, but there probably is IC2 stuff hidden in places (such as here) which I may miss.

As far as I can tell, this is fixed now in version 2.10d :)
