--> OBSE has been updated to work with 1.2 - it can be found Here
--> The UOP and UOMP have been updated with 1.2 compatibility (No Frans+UOP 2.0 ATM)
--> Hotfix for bug with incorrectly named vanilla meshes after 1.2 Here
--> Hotfix for crashing vanilla and SI bows Here
--> MathFunctions.esm, an ESM file used by many mods, crashes existing saved games and wont let users create new ones after installing SI, but can be fixed by redating it to before Oblivion.esm
--> Francesco's Leveled Creatures-Items 4.2b Has some problems with its BSA files - Fix explained Here
--> Martigen's Monster Mod v2.01 causes CDTs - Fix available Here
--> Oblivion WarCry causes CDTs - Fix available Here
--> More Immersive Sound has a problem with incorrectly named vanilla meshes - Fix explained Here
--> Natural Interiors does work now if you register the BSA files in the .ini. The fran's fix should work the same way here
--> Natural Habitat has problems with birds - Fix can be found Here
--> SM Spell Levelling has been fixed, compatible version can be found Here
--> Soya's 4 Hair Pack messes with the imperial voices, possibly due to 1.2 - A fix can be found Here
--> Timeslips custom shader packs do work if you properly patched the unedited shader files first with 1.2 and then make them writable (which in most cases requires a reinstall if you didnt backup). other shader packs dont seem to work, CatEye packs are confirmed
--> Darn UI and Dark UI w/ Darn have problems with 1.2 but can be fixed by installing and configuring This
--> It is also recommended to delete your old oblivion.ini file and let the game recreate it again, it seems to solve alot of problems
--> It has now been confirmed that any BSA files being used by an ESM type mod will not load, but any using an ESP will. the solution to this is to either unpack them, or register them in your .ini (but has problems if the BSA name is too long, this can be overcome by setting the .ini to read only)
