I offered to help someone over on SpaceBattles with a crash in retail. Running the mission through a debug version of FS2_Open gives me this
Assert: Ships[ship_index].objnum != -1
File: U:\src\cvs\fs2_open.testing\code\ship\Ship.cpp
Line: 11250
Call stack:
------------------------------------------------------------------
mission_eval_arrivals() mission_parse_eval_stuff() game_simulation_frame() game_frame() game_do_frame() game_do_state() gameseq_process_events() WinMainSub() WinMain() WinMainCRTStartup() kernel32.dll 7c816d4f()
------------------------------------------------------------------
which makes me suspect that the mission is crashing cause there are too many ships in the mission. Am I right about that one?
