Hello and thank you for your replies.
"From my observation real names shows after some time of server beeing online. Before this map is often labeled as "Deathmatch"or smth like that."
Previously I have achieved the result you have mentioned (I have added new files to "SceneObj" folder, added lines corresponding to the maps in scenes.txt and added custom names in strings.txt). I thought that I did something wrong (names weren't displayed properly), so I reverted the changes.
However, could you please specify how long the server should run, so the names are changed for proper ones? Are we speaking about a couple of minutes, hours or even days?
Thank you in advance.
