So, I'm trying to make a private pack for a handful of friends (seeing as some of the mods used won't allow me to make a public pack).
I've gotten the pack running fine, however I keep trying to add Gulliver and having problems. I've tried extracting the mod and dragging the contents in the modpack.jar, but when I do that and try to run the pack, it starts up then immediately exits to the launcher again. No official crash or crash report otherwise I would include it here.
If someone knows what's going on PLEASE help me. Also general knowledge on adding installer mods would be appreciated for future reference so I'm not asking the same question next time.
