Yes, they are all used as modifications to the game Minecraft, available for download from the modding website CurseForge. Enigmatica is a curated collection of such mods that includes a mod I'm interested in, Ars Nouveau
With hundreds of mods loaded at a time compatibility is an issue, and this is one such case. My current collection ceased running when I added Ars Nouveau to it. So the hunt is on to discover which mod(s) present an incompatibility, and thus require me to choose from a mutually exclusive set.
This list of mods with different version numbers is a first step to making the collection I have also host the mod I want. My next step will be to temporarily disable the various mods from this list to find out where the incompatibility exists.
I'll be using a divide and conquer technique. I'll disable half the mods in the list of potential version clash issues, and then try to run the game
- If the game runs, the conflict was in the disabled half of the list
- If the game fails to run, the conflict remains in the enabled half
With this list of 58 items the process of trial and error should take about half a dozen tries. Additionally, the first pass of disabling the whole list of version differences will help me determine if the issue is a version mismatch.
