The PomBase slim was recently updated to give better coverage and minimise redundancy.
Some changes chromosome organization was replaced by chromatin organization cytokinesis was replaced by mitotic cytokinesis, and some categories were removed completely.
A consequence of this is that these links no longer work. I waited a few days as I thought EsyN may need time to catch up.
Could you check that you are picking up the current PomBase slim, and let me know if the problem is at our end or your end.
