@Tarun_Dorairaj So multiple issues here.
First of all the Entity ID thing is because the game only supports a max of 256 entity class types, and a lot of modders do really bad things like do a unique class per entity type instead of controlling them via data, so they spam out those ID’s like they are free instead of the very limited resource that they are. In other words you have too many mods made by modders that don’t know what they are doing with entities and their limited counts. I’m guessing that runic mod does that same kind of poor code design, but you could remove other mods that spam out entities in a poor way if you want the runic one instead, you just need to keep the total entity class type count to below 256 because of MC engine limitations.
Second, the ambiguous recipe error is because whatever that IC2RPGAddon thing is is putting in a bad recipe, was it made for an older IC2 perhaps or is the mod just broken? ASM could fix it, or fixing the mod could fix it, whichever. Even GT6 could fix it if GT6 exists in the pack too and Greg adds that fix (though it seems odd to fix a set of mods unrelated to GT6, lol).
