I wrote a script to unlevel (or relevel) leveled lists. Since this script is generally useful, even beyond unleveling bashed patches for Requiem, here it is. Copy to a .pas file in the "TES5EditEdit Scripts" directory. While in TES5Edit, select a leveled list, or a leveled list group, and apply the script. Use a value of "1" to unlevel.
View script › EDIT: @GrantSP -- I removed the link as all @fireundubh's files are now unavailable.
Note: Remove "ClearMessages();" if you get an error. That function is available in only the latest versions of TES5Edit.
