ollama decision models all broke on 0.40.4?? "was downloaded in a format that is no longer supported"

[Apa]

'nimble:latest' was downloaded in a format that is no longer supported. To re-download, run 'ollama pull nimble:latest'

nimble, tev and clef-flash all throw this the moment ollama hits 0.40.4. fine on 0.40.3. and a single re-pull doesnt always do it either, apparently the model id has to actually change to the new library one?? confusing

Per an Ollama maintainer, 0.40.4 swapped the old custom systemone engine for native llama.cpp, and those models were rebuilt for it. If the ID changed after pulling, you're done.
