I've had problems to update MISP 2.4.94 to 2.4.99.
I followed this option 1 (and 2) from https://github.com/MISP/MISP/blob/2.4/docs/UPDATE.md and, in option1, I have this error:

`# git submodule update --init --recursive

Have someone had this error too?

Start with docs/UPDATE.md, especially options 1 and 2, and reproduce git submodule update --init --recursive. Focus on the cti-python-stix2 submodule and the missing commit reference; done means the documented update completes without the remote-ref error.
