Hi, I'm not sure if in the information page when u say vanilla compatibility test completed you meant without the Space Age DLC, but this is what my error message says when I try to enable the mod.

Running on version 2.0.32

Failed to load mods: Error while loading mod-setting prototype "ion-cannon-radius" (int-setting): Value must be a list or dictionary in property tree at ROOT.int-setting.ion-cannon-radius.allowed_values
Modifications: Orbital Ion Cannon (Space Edition)

I get the same crash now and I do have space age enabled.

did you try to reset the settings?
Kux-CoreLib 3.15.8 should resolve this issue.

Loads for me now after the Kux-CoreLib update. Thanks for the quick fix!

Yes I tried resetting the settings and that did not resolve the issue.

I have now updated to Kux-CoreLib 3.15.8 from 3.15.7 and that has fixed it. I am now able to enable the mod as well as start up a save. Tested out the orbital ion cannon and so far it has been working without any issues.

Thanks for the quick fix!
