At startup an error in the Nuclear Science mod is reported when this mod is also enabled:
16.674 Error ModManager.cpp:1758: Failed to load mod "atan-nuclear-science": atan-nuclear-science/functions.lua:167: bad argument #1 of 2 to 'pairs' (table expected, got string)
stack traceback:

Apparently the fix is a one-liner:
