I've noticed an issue with the mention system (@) that appears to have occurred since the recent update to the search functions. When using the mention system and there are two articles with the same name, it only finds one of the two to be able to link. For example, Halfling (species) and Halfling (language) only lists the Halfling (species) as a linkable option. You can still locate the other article, in this case for me, the language, by going to the list by type function in the articles page (athena), then click the copy link icon to get it, but this is a lot of extra work to find it.
I think you could create two separate types of articles and use the same name, as in my example above, create a Halfling species and a Halfling language, then try to @ them to see the results.
My bad, I see someone reported the issue in the entry before me. Sowwy.
No worries- closing this one
