Summary0004493: Crash during demo spectate freely with other players
DescriptionThere is some correlation between players being in the game during the demo and Spectate Freely crashes.

Game mode influences how things crash.
- DM crashes immediately if you're already in spec freely while another person joins.
- TDM continues as normal, until you spy on someone on a team with more than 1 active player and spec freely out of them, then it crashes right there.

Steps To Reproduce- Record demo of server
- Playback demo
- Type `demo_spectatefreely` in console when enough players are in-game

I created a new topic that should fix the crash:'https://foss.heptapod.net/zandronum/zandronum-stable/-/tree/topic/default/free-spectate-crash-fix [^]'

Please download the auto-generated pipeline build:'https://foss.heptapod.net/zandronum/zandronum-stable/-/pipelines/103735 [^]' and let me know if it fixes the crash for you.

Using the 250412-1409 autobuild:
- TDM no longer crashes.
- regular DM crashes identically to build I was on previously. (250407-1540)

I pushed a new commit to the topic mentioned above:'https://foss.heptapod.net/zandronum/zandronum-stable/-/commit/1a17b0932b3693c2988592e04faac90fe157fd03 [^]'

This should fix the crashes happening in regular deathmatch too. Let me know if it works for you.

Confirmed the (250412-1813) build work properly with `demo_spectatefreely` in regular deathmatch demos now! Did a sweep of a bunch of other modes as well to be thorough, and they all seem to behave.
(Duel, Terminator, Possession, Team Possession, LMS, Team LMS, CTF, 1FCTF, Skulltag)

I did find a semi-reliable crash via some combination of rapidly hitting binds for `demo_skiptonextmap` and `demo_spectatefreely` while loading either intermission or a map, but it's not consistent enough to me to know an exact sequence that causes it.
