The error message is on loading, and for some reason I can't copy and past it, but reading it off it says:
Failed to load mods: error while running setup for entity prototype "casting-machine-2" (assembling machine): Invalid fluid pipe connections. Connections must be at least one tile distance from each other.
And then it asks to disable Angel's Smelting, Space Exploration, as well as this mod, however, the issue only reappears when your mod is re-enabled.
