Hi. I noticed this after performing a global group rename (cf bug 27551). Information from the global users have dissapeared from Special:GlobalUsers as of now. See:
- https://meta.wikimedia.org/w/index.php?title=Special%3AGlobalUsers&username=&group=sysadmin&limit=50
This global groups have users inside, but are not shown. Curiously global groups with first letter capitalized are shown, for example: https://meta.wikimedia.org/w/index.php?title=Special%3AGlobalUsers&username=&group=Global_bot&limit=50 and all others.
Please also see bug 27551 (com. #7)
Thank you.
