I have been trying to merge all objects but find that with a list of esps as long as 249, I cannot get them to all to work merging objects without crashing testool. Here are the mods that have trouble in the merge object list:

1. GOTY Script Tidy
2. Reign of Fire
3. Suran Underworld
4. Underworld 2
5. Vampire Embrace, Realism and Hunger
6. A few more minor ones

While I have gotten everything else to play real nice together, I was ok leaving them out but found a few NPCs dialogue sessions created a CTD for me when I clicked on a particular subject. I am thinking the corresponding esp to the merged dialogue has been written over by one of my mods in my current load order. Ra'Virr comes to mind and when I ran the tes3 conflict detector program (forgot the name but very useful), it seems that quite a few mods add content to this particular NPC as one example.

Question - I am thinking of creating multiple merged object esps, then merging them in a final merged object master esp? If there is another way, I would welcome any suggestions (I cannot post my load order as I am away from my game computer for the weekend visiting family and friends).


Or is there a thread (I have searched) about how to step by step resolve conflicts and also on merging (or what mods not to merge) using testool?

Having lots of esps will cause TESTool to crash when Merging Objects, because it runs out of memory.
But, yes, you can Merge half of them first, then the other half next.

About the Dialog crash, that could very well be caused by Merged_Dialogs, which is why it is strongly suggested you do not use that esp. It has been well known to break quests and dialog.
We would need to know more about the crash (your Warning.txt following the crash) to be sure.

Haha, especially with Reign of Fire! I remember way back when I used Merged Dialogs and every NPC would get the dialog from the black dragon and then attack me. :laugh:
