Steps To Reproduce1. zandronum -host -iwad doom2.wad -file h_phobia.wad hpbar-v15.pk3
2. "addbot" in the server console.
3. "changemap map11" in the server console.
4. zandronum -iwad doom2.wad -file h_phobia.wad hpbar-v15.pk3 -connect localhost

 Looks like it's trying to access a dummy player's userinfo:

 In the version before the fix, the DummyPlayer userinfo is still accessed but no crash happens.
