meBridge.listCraftableFluid() (side-note: note the missing plural) correctly returns craftable fluids in AE2/ME, but there's no way to actually queue them for crafting. craftItem returns "ITEM_NOT_FOUND", which is probably correct. AFAICT from a skim of the code, the RS bridge has a craftFluid method; I hope adding that for the ME bridge would be easy-ish?

To be honest, I thought I added something like that
But thanks for the report
Probably the last Feature I'll add to 0.7

Confirmed this works on 1.19.3-0.7.27r. Thank you!
