Hello there,

i experienced a little error on Startup today, so i thought I'd write a little report about it here.

First things first, here is the error i experienced:
'''
Failed to load mods: kj_vehicles/prototypes/items.lua:1670: bad argument #2 of 3 to 'max' (number expected, got string)
stack traceback:
[C]: in function 'max'
kj_vehicles/prototypes/items.lua:1670: in main chunk
[C]: in function 'require'
kj_vehicles/data.lua:9: in main chunk
'''

It seems to happen only on the 2 latest versions (2.0.12, 2.0.13).
When rolling back to version 2.0.11 the error does not happen.

Edit: Sorry for the extra thread, didn't realize there already was one.

Thanks for the report. This thread is fine. Some strange things however:
That piece of code there didn't change for atleast the last 3 versions, it definitely has an error, but I don't run into it although I definitely should. So ig it must be another mod. But I can fix it nevertheless, you just need to tell me if it fixes it for you.

Pls try the update

Similar, however points to another line now.

Here's the error:
'''

Could you provide me your full mods list? If you wanna communicate over discord, my server is linked on the mods front page.

Also I'd like to see the parts in your C:\Users\<Username>\AppData\Roaming\Factorio\ factorio-current.log that say something with "Ray Col Layer"

Eh nvm, is fixed now anyway. Apparently some mods create collision layers with empty stringed order..

Just confirmed it, the new update did fix it. Thank you for the hard work!
