i think there may be a conflict with "mining-robot-2" research.
I'm getting the error at startup:
Failed to load mods: robotminingsite/data.lua:45:...otminingsite__/prototypes/miningrobot-recipe-updates.lua:11: attempt to index field "mining-robot-2" (a nil value)

If i disable Bob's Logistics Mod everything is okay :)

I can't play without bob's logistics

Looks like I'll have to pass on this mod

feelsbadman

yeah ,same ,sorry won't dl

I'm unable to replicate this error, no matter the settings used in either this mod nor in Bob's Logistics.
If this error still occurs in the most recent version, please let me know.

i just updated my mods and i enabled the option to have the higher tier sites and now im getting
Error in assignID, entity with name 'mining-robot-2' does not exist Source: mining-robot-2 (item)
