Thanks everyone for your replies! I've looked into things and I'm quite sure I've got crash fixes configured and installed correctly, all the files are where they should be and the settings are as directed. My Modorganizer/mods/SKSE did indeed have a superfluous SKSE.ini file, so I moved it out of the way. I hope it helps! I also discovered a few mistakes I made myself, specifically that I had forgotten to install Animations Package and Vanilla Skyrim LOD Billboards after downloading them (derp). Additionally I was unable to download "SRLE Extended LOTD - CR Update for 1.56 (TESTING)" as the link is dead. I don't think this would cause an issue but when attempting to perform the RSC merge I received an error and thus did not proceed with the merge. I will fix what I can for now: removing the extra SKSE.ini, installing those two mods, and doing all the steps required after installing new mods - then get back to all you nice people on how it went. Thanks again!
