I have tried nearly every possible ways to prevent this problem (including resolving mods conflict, cleaning mods, using memory patch,...) but no chance. However, until this mornaing I had not tried cleaning my save, and once I used PDTWrapper to do so I got this (by pressing Terminate Active Threads button): So I'm assuming that the game was cleaning up my character's dead body but something went wrong? Please help me, this is the only problem I have encountered my this save. Thank you in advance.
