Clicking 'yes to all' can be disastrous. When loading an ESP, you will miss the error messages that were created by your mod when you bypass all the error messages. I really hope these errors are fixed.
Exactly --- Not sure why Beth did not go back into the oblivion.esm and fix the things causing the errors before releasing the CK and the 1.4 patch - but then again the way they Beta test things has never really been that thorough in the first place -- Figure most modders would spend the time to fix errors like that if they were caused by their work but guess Beth is content with releasing it as is instead of fixing them !
