This mod adds stuff in a most careful way, in most situations, it updates the existing content and dynamically adds stuff rather than overrides content "the hard way". No conflicts were reported to me and 98% of bugs were dealt with. There may be some minor things, but they are far from game-breaking. Moreover, the EET update was provided by EET creator, K4thos 

I myself used SotSC with many other mods. If you want to know my opinion, then here it is: check your tool source. I may only guess which one you're using, but you should get familiar with these threads:

Sorry, I can't take responsibility for your install. I worked with other modders to make sure official and loved mods can be used along with SotSC. I can't guarantee it's always gonna be bugless, but the note you posted mentions things that I never heard about. However, it's kinda sad to know such pieces of information roam the internet, but what can I say - I tried to make my mod work the best and flawless way it can, I was very careful and I also use many mods so I did take them into consideration. Bah, I even added special codes to make some old stuff work properly in case there were fans of mod A or B or Z.

No matter which tools or mods you're going to choose, I hope you're going to have great fun and find what you're looking for! That is what I want players to get, no matter what.

Have a good day!
