Actually, looks like if i load up part of bob's mods by themselves (individually) with Janky Quality. It loads just fine. Seems' Bob's Assembler's is the one that's causing all the headaches.
(Could be a hard coded limit to the number of recipes the engine will allow the game to attempt to load with...janky quality probably iterates dynamically, so... 5 additional recipes for every game entity + every modded entity in an overhaul mod may just be too much lol
Sorry. I should have checked the mod's information page before posting (not just what appears in the in-game description)
...And I understand (after getting some sleep) why the recipe explosion was needed to get the intended results out of the mod. did a good job.
Done some playthrough of the mod in vanilla and it's well done :)
