The SafetyLoad.log was missing. I downloaded the SafetyLoad plugin, extracted the .ini and .dll file, and placed them in the same directory as the skse.ini ---> TSEV Skyrim LEModOrganizermodsskse 1 07 01 I then launched Skyrim via SKSE in MO (as usual), and tested fast travelling from a few places to Whiterun and Riverwood. There were no immediate ILS symptoms. I'm not sure that the issue is resolved, since the ILS symptoms seemed to be haphazard, and occurred more often after several hours of gameplay. Hopefully, I'll be able to put in a few hours of gameplay this evening to confirm that things are fully functional. In the interim, is there anything else I can do to confirm that SKSE has acknowledged the newly added files, or is gameplay testing the only way to go from here?
