i found a fix for a compatibiltiy issue between Dark matter replicator 18 and spaceblocks which comes from the fact that DMR18 uses an ore to research which means that the ore dosent have an item type but instead a tool type(since only tool type things can be used to research) which can be fixed by adding

if(itm == nil)then
    itm=data.raw.tool[rname]
end

at line 279 in the data-final-fixesl.lua file

above the itm.fuel_category~="chemical" check

this small change will probably also help with compatibility for other mods using ores for research
