Slot 4061 is already occupied by buildcraft.builders.BlockMarker@61bd0e when adding
ic2.advancedmachines.common.BlockAdvancedMachines@c30f76^ I keep getting this.
I tried them alone, they work fine, just not together.
I have AdvancedMachines_4.5_1.4.5
and buildcraft-A-3.2.2(Minecraft 1.4.5 + industrialcraft-2_1.109.113-lf )
Is there a way to fix that?
It's a block ID error, try the instructions at this post, if that doesn't work, you'll have to solve it manually.
