📋 About This Mod

This mod is a joint effort to fix the vast amount of bugs currently existing in the Shivering Isles expansion pack for Oblivion v1. 2. 0416. If you're experiencing a bug with Shivering Isles and it's not fixed by our mod please by all means report the bug to us in as much detail as possible so we can try to fix it! Also if you find any: levitating trees or rocks, see-through or fall-through walls/objects or other stuff out of place, please let either of us know in the official forums' thread. To get the exact location, use the console commands sdt 0 and then tdt, click the item, note the Cell (not PC Cell) and form ID value (the eight hexadecimal digits at the top, ie 00123ABC) and indicate what's out of place. You can use tdt again to toggle the debug display off. Thank you and we hope you have a better Shivering Isles experience!

Warning: Only use the Unofficial Shivering Isles Patch with the version of Oblivion is was created for! Using it on an older version than v1. 2. 0416 of Oblivion may cause bugs or things not to be fixed that were advertised as such!

Please report any new bugs on our project bug tracker at AFK Mods

FAQ (Frequently Asked Questions)

Q: Do I still need the Unofficial Oblivion Patch?

A: Yes, the Unofficial Shivering Isles Patch only fixes things added by the Shivering Isles expansion.

Q: Will this conflict with OOO/MMM/Fran's/FCOM etc.? Is it alright to use together?

A: Yes the Unofficial Shivering Isles Patch does conflict but nothing that is known to cause problems, other than not receiving some of the advertised fixes from USIP; always load USIP before any other mod and you'll be fine. If you're using Fran's (MOBS or non-MOBS) a Fran's version of the USIP is available here. If you're using FCOM also install the "Frans Optional Leveled Quests-SI Only.esp" available from the same location. There's also an FCOM-only version there without the Fran's Amber/Madness overhaul.

Q: I see so many red conflict with the Unofficial Shivering Isles Patch and other mods!!! Will my game explode?!?

A: Nope! The file date of Unofficial Shivering Isles Patch.esp was set way back to the year 2002 so it will load first then your other plugins, in other words if something conflicts with USIP that plugin will override USIP's changes. Note: since USIP's changes are overridden some fixes might not work.

Q:Unofficial Shivering Isles Patch.esp shows conflicts with Unofficial Oblivion Patch.esp! How come?

A: There are a few scripts that the UOP fixes that needed even more updating when Shivering Isles came along. For example, the UOP fixes a bug with the scripting for the Gray Cowl of Nocturnal, but Shivering Isles added another bug
