When starting factorio with you mod (and others(e.g. NuReact)) i get the following error message:

Failed to load mod "Signals 1.2.14"
Signals/prototypes/signals/power.lua:127: attemp to index global 'stop' (a nil value)

Would you mind copying and pasting your "mod-list.json" please?
Knowing what mods are installed will help me debug this.

Also, if you have made any changes to the mod, e.g. the config file, I'll need to know that as well.

sure, no problem, but its long ;-), i also did quite a few changes to some of the mods:

factori version: 0.14.17

]
}

changes i did:

• angels ore silos (capacity increased to 1000 slots)
• angels smelting (removed maganese ingot from aluminium and titanium recipe)
• bobsangelthon (same recipe change as before(overwrite), another fix in a recipe
• bobsconfig (raw productivity modules for everything enabled)
• landfill (dirtdisplacement and throwrocks deactivated)
• marathon (recipes for mk3&4 chemical factory and electrolyzer fixed)

hope, this helps. however, i think none of the changes i did to the mods should affect your mod. i also had a quick look into the file mentioned in the error message, and the mentioned line points to some graphics from reactor. this is, why i mentioned nureact as mod. i think it is partially based on the reactor mod.
if you need further information, let me know

Ahh, that's the problem. Reactors is an optional dependancy, you don't have it. I'll work on fixing this error, but for now to get around it you can change this line in my mod's config file:

REACTORS_ENABLED = true -- Enables / Disables support of "Reactors" mod

to false, instead of true.

Would you mind trying to start the game, then posting your factorio_current.log?

ok, i disabled the support for reactor in the config and it works!

the log after the changes? or before?

Before the changes, please.

It's definitely NuReact. Not that NuReact is a "bad" mod, but I really suggest switching to using the Reactors mod alone. NuReact doesn't seem to be updated as fast as Reactors, seeing as how NuReact was updated 2 months ago. The Reactors mod has been updated QUITE considerably since NuReact was created, and now includes extra virtual signals that NuReact doesn't (and renamed a few, which is what is causing your problem), along with a lot of new features.

I can still add conditions for NuReact's virtual signals to be supported by my mod, but I don't know if I want to do that for a mod that doesn't look like it is updated anymore.
