Sorry for the (very) late response. I've taken a few months off from all my non essential projects. As two of my income streams have completely dried up due to world pandemic. I did initially just make a quick patch to let the mods run in v18 (MSP and CE are my two factorio projects atm).
MSP should be compatible out of the box with any combination of bobs angels or zelos (omnimatter) mods. this gets a bit more complex with additional mods are added on top but i also tested some of the big name ones as well. For more detailed resolution, i'll need info on what selection of mods (and versions) are being run; as a general rule i don't support mod groups that have outdated mods as its just extra work to try and locate/resolve something that may have already been patched. If everything in your folder is updated and pack 18 still does not have a technology that unlocks it (also need to know if you're running with the omniLib or without, as it VASTLY changes how the mod performs....this is intentional/by design)...i can start looking into it. Also a look at modsettings can give us the answer we need. other mods that alter modules could also be to blame, which is why i need to know what other mods are being used.
Some recipes are not made in an assembler, some require the chemistry lab. FNEI is your friend. If a third party mod adds a fluid component to the recipe after my mod loads and changes it's crafting location somewhere during the middle of loading, that could also be causing an issue...basically i need more modpack-detailed info so i can replicate the issue and trace its source. sorry for the lengthy explanation, but i feel it's the least i could do . Happy factory building!!!
