Hi, there!!
I found same error and found answer from a month ago... here posted by twisteddiana
defines.inventory.player_armor doesn't exist. Should be replaced with
defines.inventory.character_armor

Thanks. I will try it.

Also I made very similar mod, fix for this one, but insted of shild you get 2 exoskeletons.... if you want I can send you the link

No need for it. I just need to click on your name. ;)

Correction has been made.

Thanks!
This just because it's easy ask for fix, but it's easy too to be grateful for it when done. :)

Got a similar crash (0.18.14) when making a sandbox world. No player so no character to give stuff to (don't know if or how you could fix I just disabled the mod for building in my test environment)

This should be sorted out now if anyone has more problems.
