Alright so i made an .esp i wanted to use a master. I used Wrye Bash's copy to .esm feature and loaded that .esm and oblivion.esm up and did a small edit and tried to save - only to have the CS crash. I thought alright that wont work so ill esmify the file, so i did that, made another small edit in the file and tried to save a new .esp, and it crashed again. Any ideas on what to do? I also used the TES4Gecko to merge a few files in, but that shouldnt have an effect right? if any1 needs any extra details just ask. thx

Disregard this i figured another way out. i used TES4Edit to copy all the records into a blank.esp, loaded it up in the cs, made a small edit and saved - and it worked

Self solved.
