--- Comment #6 from TOM l12436@yahoo.com.tw --- Add more explain.
"You need to load skse_steam_loader.dll this first. problem is come from this." this mean if you did not use -forcesteamloader, in some Skyrim, it may direct load skse_1_9_32.dll which I also found It is normal, but SKSE require skse_steam_loader.dll for some feature.
But If you load skse_steam_loader.dll by add -forcesteamloader, which will load skse_steam_loader.dll first. In 2.18, it will only load skse_steam_loader.dll and then stop which is abnormal
