I've spent all day making, cutting, editing, converting, adding dialogue for actors. I'm on my 4th merchant with custom dialogue, all other 3, 2 Khajiit and 1 Argonian work perfect so I know what I'm doing. Just have this 1 actor that for no reason I can see won't use her goodbyes. She "lips" her merchant dialogue but at the end, well take a look...

I've remade the .lip again and again, checked the file name of the .wav, .xwm and .lip so that they are all the same. She has 3 possible goodbyes all are checked random, goodbye and has lip file. I've used TES5Edit to remake .seq file a couple of times too. Her dialogue setup is no different than the other merchant actors, none that I can see after an hour checking and re-checking,
