2.2 New Life Rule - Do not return or interact with the area of your death (between two tunnels) that you died until 3 minutes has passed. There is a timer at the top of your screen. If you died in the spawn area, leave it promptly through the nearest tunnel or AFK at spawn.
Even if your timer was at 0 seconds just as you reached your death point you are not allowed in the same distracted meaning you broke NLR coming through the district to reach your death point for 0 seconds. Nexize was right to warn you. He did not warn you about fading doors. He even gave you a chance to back away.
