Lords of Cyberspace crashes mbbsemu on Sysop cmd #599

Open Blixxky opened 7 months ago

Blixxky commented 7 months ago

Reproducable by using these commands to enable Sysop permissions (requires SYSOP key by default):

permit 0
permit 1
permit 5
edit p

Then pressing enter or taking other action will crash Mbbsemu

any key
