If you download https://huggingface.co/TheBloke/Mistral-7B-v0.1-GGUF/resolve/main/mistral-7b-v0.1.Q4_K_M.gguf yourself and put it in the game directory next to the EXE it should solve the download error. It seems like it is asking for the data from the server but getting like a bad bit or something and immediately bailing out because I never wrote retry code.
