Thanks for the response!
I honestly hadn’t thought to ask HBM for an update - I tend to assume that 1.7.10 projects are abandoned, and I thought it might be easy enough to build out the error handling in WeightedInventories. I’ll definitely ask now though!
You hit the nail on the head with Windows/Eclipse guess lol. I installed Git for Windows and ran the commands in a Git CMD window, but individually in sequence as they are listed in OvermindDL1’s guide. (I tried re-running them as a single command, and didn’t see any difference.) I guess what I expected was to get an “eclipse” folder at the end, where I would point the workspace, but I don’t see one, and I’m unsure how to proceed.
