I have a play with SE+K2..
There i have a electronic-part of K2 which is still of old recipe.

Albeit ok, but i think it would be better fitting if one use a green/red board or the thingies (collection) in itself for these recipes.

i am pretty sure i don't include your mod in the present run, but i sure think using it for future ones..

can you press f4 while in game, then check 'show debug info' and give me exact name of recipe/item and which mod is it that you want me to check out

for exampe :
express splitter (the blue one)
flying robot frame
....

what do you want to see though?
splitter uses advanced circuits and robot frame electric circuits (at least in vanilla or SE)

if krastorio is changing their recipe then that's how it will be

its ok

i just was surprised that your mod adds some particular eletronic components, but still i have seen the ones from K2 in the recipes.....
I would have expected, that this EC were changet to some particuarily items from yours so completely removeing the K2-EC

Just was noticable by me

i see now, yeah i guess it's different approach. i like having it the way it is. although my mod has 4th level circuit used for advanced machinery.
