when both this mod and Dea Dia are installed, the thorium 229 recipe added by this mod gets completely disabled, and the dea dia thorium becomes the only source. this is problematic, since the thorium from that source is locked to a significantly further progression than this mods (requiring both vulcanus and fulgora, compared to just purple science), along with it locking out tier 3 modules until you complete up to thorium in dea dia. some kind of fix would be an option for the advanced reactor without the precision timing circuits, possibly just using a lot of blue circuits instead?

Since Dea Dia is (according to its page anyway) currently still in alpha and undergoing reworks, and thorium and nuclear technology in general seems like one of those things that is being reworked this issue might be better tackled on Dea Dia's end. Once that mod is more stable, if this issue still exists, I might revisit it.
