Failed to load mods: Technology worker-robots-storage: Infinite research followed by level 5

the error seems to be with the name [worker-robots-storage-4] as changing it to [worker-robots-storage-infinite] fixes the error

Edit: never mind, seems like it was a mod conflict error, I apparently already have mod that was adding a few extra levels of worker-robots-storage

can you please link the mod so i can mark it as incompatable?

It adds a fixed amount of extra worker-robots-storage, so in theory, you could perform a check if mod is also enabled, then label your levels accordingly, but that is obviously more work for you and well beyond the scope of what is expected.

Due to BigBags being seemingly unmaintained at the current time, I have created a fork of the mod that allows the additional levels of worker-robot-storage to be disabled with a config option, which enables compatibility with your mod again.
