(or have you tested with *only* CLS and a mod that is missing a coremod?)

Ah. You can't do it in 1.7.10 atm, but you WILL be able to do it with BLS 1.4.x for 1.8. When I stop porting Buildcraft for a few days,...

I think this might be caused by the CLS config option `smooth_init` defaulting to `true` rather than `false` - can you check to see if changing it does anything?

No, I was hoping smooth init was the cause of this. Setting it to true would probably make it much slower then.

I'll try testing it locally - have you made any changes to the modpack (other than adding CLS) from what you're testing ATM and release 0.41.1?

Ok, from some local testing: - Forge (default): 8:18 - Forge (disabled): 7:23 - CLS (smooth_init=true): 9:39 - CS (smooth_init=false): 8:46 So yes, CLS seems to make it slower. I'd...

REI doesn't have the functionality for this yet: https://github.com/shedaniel/RoughlyEnoughItems/issues/115 (and a few others). When REI is updated then I might add support for it though.

It looks like this is caused by LBA being accidentally incompatible with UniversalComponents, although we're looking into this now.

@1a2s3d4f1 That's a different crash, and should be reported to Astromine (https://github.com/Chainmail-Studios/Astromine/issues).

Unlike BuildCraft (which I put a lot more effort into) I don't really care about the performance of SimplePipes - it's a quick copy-paste of buildcraft to check to see...
