» Tue Jun 19, 2012 7:20 pm Also of note is that esms can modify other esms -- within certain limits. The main limit seems to be that one esm cannot add items to worldspaces defined by another esm. (Or rather, it can't do so safely -- since doing so causes landscape and buildings to disappear during gameplay.)
(...)
When one esm modifies in any way a worldspace cell of another esm, the land bug occurs in gameplay. The land bug is where the local land textures (and often static buildings, etc.) disappear in gameplay. This happens not just in a few isolated spots, but typically everywhere.
I tested if these issues still appear in Skyrim, and so far my conclusion is "no". I have my worldspace in MiddleEarth.esm and a huge generated region with thousands of references in a file called Rohan.esm. I also edited terrain heights in Rohan.esm. Both ingame and in the CK everything shows up perfectly fine, no disappearing landscape or buildings (I placed a few manually).
The fact that Bethesda uses an Update.esm for their patches seems to support the hypothesis that there are no more issues when an ESM modifies a worldspace or contents of a worldspace in another ESM file. I don't want to jump to conclusions though, so hence I ask here: Have any of you tried this as well and if so encountered any relevant problems?
