Supernode nodes don't seem to automatically forget about Edge nodes

[ltxhhz]

supernode file: https://github.com/lucktu/n2n/blob/master/Windows/n2n_v3_windows_x64_v3.1.1_r1255_static_by_heiye.zip version:

Welcome to n2n v.3.1.1-71-g9618512-dirty-r1255 x64_static for Windows

I installed supernode on Windows Server 2019.

According to the documentation here, supernode should forget about the edge node after 2 minutes.

{"_tag":"1","_type":"end","cmd":"edges"}

the output shows that the '192.168.33.100' node is more than 2 minutes behind the other node 'last_seen', which results in this edge node not being able to be re-registered
