Luke, have you even played Final Mod Pack in its final iteration? It went through many important changes, even up towards the end of development. If you played an older version, you might give it another shot. If nothing else, it's a highly diverse mod pack which probably has plenty of elements you've never seen.
I can provide some help with error reports. Usually they point to a part of the ruleset, but if you ever get confused, tell me the error on Discord and I might be able to find it. I've gotten good at that. Now, when you get the dreaded segmentation fault error, it won't give you the slightest hint where it happened. These seem most commonly to come from changing map files, tilesets, and connected lists. It seems to happen when you rearrange a list of items, or change the size of the list. It helps to always check your work before you wrap up some map or tileset editing, so that when you get the segmentation fault you can narrow it down to your most recent work.
But if you need help with a segmentation fault, let me know and I'll see what I can do.
