What should I keep an eye out on the log files? Bit of a fun fact: The above conflict I talked about, the berry bush from Biomes of Plenty and Gregtech electron circuit? NEI told me that the electron circuit I got (due to item ID conflict) was somewhere around 25xxx ID range, but the configs both said they were 21003. Is NEI lying or is there another reason for that?

I come here with a problem. For the moment, everything works fine on my own modded game (about 145 of them running). However, it seems I still have ID conflicts that's hard to spot until something durning crafting or interacting with the world happens. Example, I am running Biome's of Plenty and it is giving me Gregtech Electron Circuits from the berries bushes. That I have fixed already, but my question is: Is there a config option or something that will keep telling me about those conflicts? Or does it say somewhere in the .log file?
