Im not very surprised you had fatal errors as I havnt really looked into the pack in terms of the file structure and configs yet, I was just trying to get it to actually let me add the pack to my launcher and download what I had in there. The web server is one I am hosting myself, but the zip files are on dropbox. Now when you say they are structured wrong, I am guessing I misread the instructions for solder for the repo. If I understand you correctly, as I currently have it, for example, bigreactors_0.3.4a.zip currently only contains bigreactors.0.3.4a.jar. You are saying that jar needs to be in a folder called mods, very similar to the zip structure of the other modpacks? And while we are on that topic, do you recommend making a separate "mod" containing all the config files? Or should I include the configs in the individual mod zips?
Sorry for the confusion in the previous posts. I am glad that others were able to add the pack to the launcher, I continue to be stumped as to why I cannot add it. I will look more into that issue later on.
Thanks for your help.
