There is 2 questions I do have, first, could you clarify this statement here? Do you mean while in the merging process, don't leave out the master mods that aren't going to be merged inside a group of mods that I'm going to be merging, because the renumber formIDs option will go haywire? Also what is the "group" that you're referring to? When I load the mods I want to merge, TES5Edit loads up the masters along with it, but when I apply the script, I just select the specific esps I want merged. My second question is, how best should I go about merging the ETaC Patches and the Populated Series together? I've heard(including from the reports) that they merge fine, so there must be something on my end that's going wrong, and they're currently the mods on my list that use the biggest amount of esps, which would free up a significant part of the load order if they were merged instead, even in two esps instead of one. When I try merging the ETaC patches, well there is at least one I found errors with, so I did not include it, however when I tried merging, one of two things happened, either certain records did not survive the merging(which I heard is a fixable process), or I found errors after the merging, and could those errors be because I chose to renumber the formIDs for patches? Or am I missing something else entirely here?
