All recipes with multiple fluid inputs or outputs are bugged in SP on latest 2.0.9.0 RC1 that uses GT-PlusPlus-1.7.05.67.

Expected Behavior

Example Water:
(Fluid) Water with a circuit on 1 should give Oxygen and Hydrogen (both fluid/gas).

Current Behavior

that recipe does not work and is not in NEI either. Instead the Large Electrolyzer uses the single block recipes:

In particular, this means that the recipes require cells and cannot be done with fluids only which was a great feature about them.

The same is true across all the recipes of the Large Electrolyzer and Large Centrifuge. Have not checked other Multis, but if there are similar recipes they might be affected too.

Possible Solution

no idea of the cause, so no idea for solutions
