I regularly recompile llama.cpp but after having done so today my existing setup stopped working. llama-server started throwing an error 400 on the chat template in the Ornith 1.0 35B model I'm mostly using.

Couldn't find anything (except a closed stale issue on llama.cpp that seemed slightly similar) so I followed the advice from another posted there and installed the linked "fixed" Qwen chat templates.

That worked, so, just posting this here in case it might help someone else too.
