Hi

I have the following error preventing the game to load:

Failed to load mods: ...tructron-Continued__/data/constructron_pathing_proxy.lua:134: attempt to perform arithmetic on field '?' (a nil value)

Hi

Unfortunately the stake trace does not tell me much, would you be able to follow a process of elimination and work out which mod in combination with Constructron caused this issue?

I tried to do that. Usually it works, but in this case it was quite annoying.
It seemed that I finally managed to narrow it down to 1 mod that if loaded with Constructron-Continued_2.0.30 causes the error.
But then I tried to load only those 2 mods together and the error didn't come up.
Now I think that some mod combination causes the error, not just 1 mod + Constructron-Continued_2.0.30.
This means that I probably won't be able to figure it out because of too many combinations. Sadly I have lots of mods and it takes minutes for the game to start.

I don't have coding knowledge. Would it be possible to place some debug code into Constructron-Continued_2.0.30 so it displays more information?

Edit:
Some data I can provide and might be helpful:

The mod ‘UPSFriendlyNixieTubeDisplayFixed_0.2.9‘ might have something to do with the error.
All my mods including ‘UPSFriendlyNixieTubeDisplayFixed_0.2.9‘ + ‘Constructron-Continued_2.0.30‘ causes the error.
All mods Oncluding ‘Constructron—Continued_2.0.30‘) except ‘UPSFriendlyNixieTubeDisplayFixed_0.2.9‘ works.
Only ‘UPSFriendlyNixieTubeDisplayFixed_0.2.9‘ + ‘Constructron-Continued_2.0.30‘ + ‘flib_0.16.2‘ (required for Nixie) also works.

So it seems that ‘UPSFriendlyNixieTubeDisplayFixed_0.2.9‘ and some other mod(s) in combination causes the error in
‘Constructron—Continued_2.0.30‘.

Unfortunately I don't think there isn't much possibility on your suggestion in data stage but the issue is rather odd as this is the line that is erroring indicates that a prototype has no collision box.

Constructron-Continued/data/constructron_pathing_proxy.lua

Line 134 in 0cfe946

local width = collision_box[2][1] - collision_box[1][1]

If you can get a significantly cut down and reproducible method, I should be able to work with it.

I edited my above comment with some data, hopefully that helps.

try this;

load in with all but Constructron and then see what is editing the nixie mod entities

This is what the tooltip of a nixie tube looks like with all my mods except Constructron.
But loading only these mods and Constructron the error doesn't appear.
