Problem with UD-IQ3_XXS model loading in llama.cpp?

I downloaded the file for "Qwen3.5-35B-A3B-UD-IQ3_XXS" the sha256 matched but trying to load it into llama.cpp server gave the error:

srv load_model: loading model '.../Qwen3.5-35B-A3B-UD-IQ3_XXS.gguf'
common_init_result: fitting params to device memory, for bugs during this step try to reproduce them with -fit off, or provide --verbose logs if the bug only occurs with -fit on
llama_model_load: error loading model: tensor 'blk.8.ffn_up_exps.weight' data is not within the file bounds, model is corrupted or incomplete
llama_model_load_from_file_impl: failed to load model
llama_params_fit: encountered an error while trying to fit params to free device memory: failed to load model
llama_params_fit: fitting params to free memory took 0.10 seconds
llama_model_load: error loading model: tensor 'blk.8.ffn_up_exps.weight' data is not within the file bounds, model is corrupted or incomplete
llama_model_load_from_file_impl: failed to load model

Perhaps this is a llama.cpp issue. However the larger file "Qwen3.5-35B-A3B-UD-IQ3_S" worked fine?

Closed. My mistake. The working directory should have contained a symbolic link but instead had a truncated file. The sha was from the downloaded copy on a data drive. My apologies.
