Server crash while executing FCNPC's adapted missions

[NexiusTailer]

Describe the bug
When I executed missions script (adapted FCNPC default sample, will be linked below) and tried to close the omp server window (i.e. tried to shut it down normally), it crashed before the exit.

To Reproduce
Steps to reproduce the behavior:

1. Download and compile this adapted missions.pwn script (.rec files here)
2. Add any bare gamemode and crashdetect plugin, add missions filterscript into server config
3. Launch the server and connect to it, spawn, then write in the chat /mission start
4. You'll see an initial cutscene with some gametext title, now you can go to your server and turn it off
5. It crashes with all logs and .dmp file provided

Screenshots and/or logs
Server log file: log.txt
.dmp file: omp_minidump.dmp

Release version
Latest release build 1.5.8.3079

Looks like it crashes even after you pass/leave the mission and try to turn down the server, another case is this:
log.txt / omp_minidump.dmp
