Our squad has properly created squad.xml file available on the web. It seems that with anyone else, squad nic (tag) is shown except for myself. Squad nick is correctly configured in my Arma3 profile.

I'm forced to use alternative directory for Arma3 profile, as the Documents folder is located on home network server and Arma3 cannot write to that location (\\server\share\path)

I have following profile folder defined on the Arma3 Launcher:
C:\users\<username>Arma3Profiles

This folder contains following directories:
MonetizedServersCache
MPMissionsCache
OfficialServersCache
squads
Users

Folder squads contains one subdirectory (our squad name) and there are all the *.paa files from our squad members.

Defect: The squad nick (tag) is not displayed next to the players name on the Role assignment when separate profilefolder has been defined.
Defect: The squad nick information and picture are not displayed on map / Players-menu when separate profilefolder has been defined.
