Problem (Short version): My game misses dialogue lines from mods, sometimes vanilla dialogues and often written text from books (both vanilla and from mods), also voiced lines from the initial cutscene of Helgen. Problem (Long version): Like 3 weeks ago I decided to make a new build of Skyrim SE and start a new game (upgraded the USSEP and few other mods). After the normal start, I noticed that: - Some lines of dialogues with NPCs were missing. One to three lines of dialogue (as far as I remember). They are mostly the lines from mods, but often vanilla ones are included (for example, the first one or two option of dialogues with Gerdur are missing, usually the first one is the one to ask for supplies she can share). - Followers (not vanilla) often give me just a couple dialogue options (the two from Flower Girls to initiate or refuse courting, or alternatively the one to refuse courting and the "follow me"). - The courier (from mods of course) follows me reciting the classic lines but doesn't give me any letter, so he keeps following me. - Finally, books and notes are blank (always the ones from mods, sometimes the vanilla ones too, like the two books of "Brief History of the Empire" found in Helgen's fort). Now, I thought there was a problem related to a mod I had installed, so for the last 3 weeks I basically kept uninstalling and installing mods and at one point I also zeroed the whole installation and reinstalled Skyrim from zero (the problem appeared again, so I can presume the installation wasn't corrupted but rather two or more mods punch each others). Since I ran the whole Helgen section a lot of times what I noticed is that when the problem is bound to come up sooner, the initial cutscene jumps some of the voiced lines (only certain ones). It's a sort of symptom, if Helgen's cutscene misses lines, the game is broken, if the lines are all there there's a chance the game is not broken (often it is anyway). Just for fun, these are the missing lines (crossed ones are always missing in a broken build, underlined ones are missing only sometimes) At this point I'm out of ideas, since I understand only the bare basic of all this. List of plugins All mods were cleaned with SSEEdit, no warnings Computer is an intel i3 16 GB ram. Windows 16. Skyrim SE is fully upgraded. The computer ran the game decently (with some FPS drop) until the start of the problem.
