DeepSeek local quantized version exhibits weird CoT: normal output but caveman speech

A developer running a local q8 quantized version of DeepSeek V3 (0731) via unsloth and llama.cpp noticed a bizarre reasoning behavior: while the final text output is perfectly normal, the model's internal chain-of-thought (thought text) is highly unusual. The CoT uses the pronoun "We" and breaks down into what the user describes as "caveman speech." The poster is asking the community if this is an expected model trait or a misconfiguration.
