Gives construction and/or logistic bots 100% resistance to most types of damage.
The idea of this is to prevent bots from dying when they arrive at your base defenses to repair walls/turrets or place new landmines, and die as a result of biters still attacking your defenses.
Bots are still mineable. By default, logistic bots are not invincible, but this can be changed via mod settings.

I prefer bug reports to be made in the mod portal or on Github, but I've made a Discord server if you just want to discuss and ask questions about my mods: https://discord.gg/Bkteq2kheD
