⚠️ Common Mistakes
- Installing multiple mods that modify the same files without checking compatibility
👍 Pros
- Massive community backing (58,829 endorsements) — this is the go-to patch for Shivering Isles.
- 2.2 million downloads prove it's practically essential for anyone playing the expansion.
- From the same team behind the Unofficial Oblivion Patch, so you know it's quality work.
👎 Cons
- Only covers Shivering Isles — you'll still need the main Unofficial Oblivion Patch for the base game.
- Last updated in May 2026 — might not address any newer issues if Bethesda ever patches again (unlikely).
- No detailed changelog in the description — you won't know exactly what's fixed until you dig deeper.
