I get the following error in the crash report when trying to use a big reactor with one of the new flux-plated fluiducts

Must be latest cohf core, latest big reactors?

It's FTB Infinity 1.2.0.

Bigreactors 0.4.1A2
Thermal Dynamics 1.0.0RC1-69
COFH Core 3.0.0RC1-181

Also reproduced with version 0.4.2A2 with no other changes. It seems to only be the flux-plated fluiducts and not any other version of the ducts.

sent it to the other side as well? Its might be a bug in thermal dynamics.

There's most likely been an API change in the new versions of the CoFH Energy interfaces. I expect I need to update BR's Energy interfaces to work with the RC1 versions of the CoFH mods.

Going to do the best I can do get something out for this, but this is a really busy week.

The API change has been in for months. This isn't anything new.

I think you're actually in the clear and it's on TD's end. Checking.

@KingLemming has fixed this in Thermal Dynamics, please upgrade to Thermal Dynamics 3.0.0 RC5 (or newer).
