Firstly, thanks for your help. Yes, I am using the latest script merger (v5.1). It's solved all the conflicts (including 2 xml conflicts) so its showing none right now. Yes, I checked all my mods are 1.10 compatible. I installed them 1 by 1 after I updated to 1.10 (verifying files after the update as well), and they all work. Some texture replacer mods were not updated to 1.10 but they don't need to be as I understand. They still all work for me. The skip movies mod is a new one, not the old one I'm sure you're thinking about. It's this one: http://www.nexusmods.com/witcher3/mods/358/? I'll try disabling it though and see if it helps. Oh, I asked this question in another place and one person did tell me there was a soft limit of around 50. Not sure if he's right but if say you have 70 mods, it must be something else. Or perhaps it depends on the type of mods you install.
