I don't doubt that they had trouble with Yogscraft's pack... It's like that whenever you make a custom pack for yourself, fix one bug by updating Mod A, which makes Mod B crash. Update Mod B, which nerfs Mod C. Update Mod C makes Mod D redundant... Etc etc. Keeping a personal/private modpack updated is... Painful at time. This I know, from experience.

Also, regarding SOI, mods can easily corrupt a savefile (In particular older mods, like those that pre-date the /mods folder.), something learned from frustrating experience.
