Been playing the pack with a friend and its been a blast, only two issues I wanted to bring to your attention is the bioluminescent tooltip bloat caused by tenebris prime and two redundant assembly machine mark 4 analogs. The tooltip bloat is already solved by a separate mod called 'Tenebris Prime Tooltip Debloat', and I'm using it myself, but I figured you might want to add it to the pack for general use. As for the assembly machine mark 4 analogs, Hydaryis and Advanced Aquilo both add upgrades to the assembly machine, but they are both completely outclassed by the advanced assembly machine from Krastorio 2. Its available much much earlier and is around 4 times faster. Its cheaper as well, which unfortunately makes the other two completely irrelevant.
The easiest solution would probably just be to remove the two subsequent assembly machines, and the Aquilo one already even has a config option for it. Alternatively, the krastorio version could be nerfed and the other two buffed, turning it into a progression chain like belts, but I have no idea how to do that so I certainly won't argue for it.
There are also similar issues with some of the personal equipment (most notably the mixed oxide reactor from cerys) and I believe one belt variant, but these are not nearly as important in my opinion.
Again, been having a total blast with the pack!
