So I'm playing the World of Dragons modpack, and my world keeps crashing after the last night's update. I have added a couple extra mods that the pack didn't include(namely refined storage and storage drawers(modpack now includes SD)), but all was running well before the update. Now I'm just confused.
3. Now crashing when third-party modpack was updated that included the extra mods
The easiest solution is to remove the extra mods you added to the balanced and configured modpack. There is no guarantee that adding extra mods to another's modpack will ensure the modpack continues to operate normally.
