Acquiring missions momentarily freezes the game or fails mission initialization, depending on world options for city

Expected behavior

Either a notification that the mission is being generated or don't hang.

Actual behavior

Hangs at 100% cpu usage for a variable amount of time on my desktop with i7 @ 4GHz. Sometimes it will hang for 3 seconds. Other times, it hangs for nearly a full minute and "Unable to place all configured specials, some missions may fail to initialize." is added to the message log. See

Cataclysm-DDA/src/overmap.cpp

Line 4377 in dbc349e

add_msg( _( "Unable to place all configured specials, some missions may fail to initialize." ) );

Steps to reproduce the behavior

• Create new character in shelter
• Increasing "Size of cities" and "City spacing" world options seems to exacerbate the issue to the point that missions consistently fail to initialize.
• Accept mission from terminal in shelter

[kevingranade]

The mission in question is probably important, some missions kick off a search for a building, which is probably what is causing the delay.

[lucianposton]

I started a new character in a new world and picked up the terminal mission. This time the game hung for nearly a full minute.

For this world, the Size of cities was 8 and City spacing was 8. Perhaps that makes it more difficult to find a suitable location to place the mission.

edit: I was able to reproduce the issue again with another new world with those same world options set to 8. Added this info to issue description.

Anything over 6 for these options causes missions to fail initialization.
