Thread:Project:Support desk/RandomInCategory

I used to use something like http://www.mediawiki.org/wiki/index.php?title=Special%3ARandomInCategory&category=Template_extensions - it worked in 1.24wmf14 but is gone in 1.24wmf21 (2691b4d) (same version as here on Meiawiki). On mediawiki.org it just redirect to a help page, on enwiki it redirect to special:Random page in category.

Is it just gone, or is it a bug?
