I saw your message in the description about how the prod and quality modules do not render on the beacon sprite. I figured this was fixable, so I fixed it. My suggested colors are pulled from the game icons, but feel free to tweak them if you think they don't quite match.

I also would recommend removing the dependency on Space Age, as none of the changes depend on it. I would also recommend changing the dependency on Quality to optional as well, as it only takes minimal code changes.

My suggested changes are below (I'd be happy to make a pull request if you were to set this up as a Git repo):

My change can be easily integrated, too. Replace the "static" v.allowed_affectswith:table.insert(beacon, "productivity")`. Then you only add a new value to it instead of replacing existing values.

Please replace [code] and [/code] with 3 back-ticks, then your code is shown properly. And your mod excludes other mods that add more module tiers, like MK4/5/6.

Thanks, edited.

Both good ideas. I added the first to my suggested code, and switched the filtering of modules to do a string starts_with search instead of hardcoding the vanilla modules.

Top! Thank you.

Can you please rename k to _? The _ means that LUA should "trash" it (forget its value).

The _ means that LUA should "trash" it (forget its value).

That is not actually true, it is simply a convention. But it is a valid convention, so I have done so.

Ah, thank you. I was not aware of it that it is just a convention.

Hmm, my fix isn't working?

Ah, I missed to use the key allowed_effects. So v.allowed_effects is the correct one, not just v. EDIT: Only in my local files.
