I forgot to say, repeat steps 2 and 3 a few times, over a time span of an hour.

You're going to have to supply us with some more information:

* WADs used
* Maps played (e.g. MAP01, MAP02)

And please upload a crash report if you get one.

I did some work on the wads, and removed all my scripts (except the main one).
It seemed like the server was running fine for a while, but then crashed.

Now, things have gotten worse; I have no idea why. But now the server will crashed immediately on the first teleport-to-map done.

It crashed the same way, today too. On the first teleport-to-map, to HUB.
'http://static.painkiller.allfearthesentinel.net/logs/c84a51c5861dc46133ed6010003a0486.txt [^]'

Both have same error message: zandronum-server: /home/skulltag/BestBot/BuildStuff/zandronum-stable/src/p_sight.cpp:649: bool P_CheckSight(const AActor*, const AActor*, int): Assertion `t1 != __null' failed.

Edward-san says this is a vexing bug.

Nevertheless, this bug is having a huge impact on me. The server is crashing, and I have no idea why.

What is P_CheckSight() anyways? Should I change my HUB map so that players start inside an empty (no items/actors in it) room (with a door) first? Or is P_CheckSight() still going to execute for player spawnpoint actors...

This is the HUB map:

A linedef with special action 74 is used for the "Teleport to Map" from another map to HUB map, or vice versa.

Yeah, it happens when zandronum is built in Debug mode and with specific mods. I and the TSPG admins fixed this by building the server properly in Release mode. This should allow arkore to reproduce the crash again.
