Nelson introduced chat fade with his 25 May 2018 patch. What this means is that you may miss important messages. The current workaround is to edit one line in your preferences.json file and restart Unturned. On Windows machines the file can be found in C:\Program Files (x86)\Steam\SteamApps\common\Unturned or C:\Program Files\Steam\SteamApps\common\Unturned Open preferences.json with notepad or any other basic text editor. You should see a line that says "Fade_Delay". The default value is 10. You can change this number to anything but if you want you chat to persist then set it to 1000 and save. Once you restart Unturned your chat should persist. I don't deal with Macs so a Mac user will have to give the default path of the file. I can then post it here. Thanks Nelson.
