Okay, here is what is posted on the 1.8 changelog for Merge Plugins: "Renumbering options: A new option called "Renumber conflicting FormIDs" has been added. This is the best of two worlds in that it only renumbers the records that need to be renumbered to avoid fatal conflicts (duplicate FormIDs), but doesn't renumber everything so esoteric issues relating to renumbering FormIDs are mitigated. You should always use this option, resorting to "Renumber all FormIDs" only if merging with "Renumber conflicting FormIDs" isn't creating a functioning merged plugin. You should never use "Don't renumber FormIDs" unless you know what you're doing and are prepared to face the issues associated with duplicate FormIDs." I will continue to use my set up with 1.8 and 3.0.33 experimental and use the "Renumber conflicting FormIDs." I'll do a little testing once I'm done and see if everything is functioning properly (which it should I would think.) Also, with the end in mind, there are a few mods that I personally would like to try to incorporate after using this guide. Is there a good resource for using Wrye Flash, particuarly about Bash Tags and how to use them for merged mods, like you do in this guide?
