Tool built my map but here's one problem: Halo closes every time I try to play it on LAN
(to test it).

Things I have on the map:
Halo 3 Weapons and Equipment
No Grenades on mao
A lot of Flood AI(20)
4 different spawn points
Flags for CTF and Oddball (weapon type not specified)
Device Machines
Halo 3 Spartan Player Model
Gephyrophobia Sky
Uses Spooky Hollow BSP

mmm i would say to you that in sapien save another version of the map eliminate all scenery's or ai and see if it works if it does the problem is in the category you erased and try to see what was
causing the issue in the tags just erase all tags in one category and do this until map works

Erasing the AI is unacceptable.The is no scenery except the stock scenery.When I compile the map,it compiles successfully.

you dont need to eliminate the encounters just erase one by one the ai until map can me opened ingame then change the ai and it should work

I erased all encounters,vehicles,devices and scenery.Still not working.

i hope you make a scenario back up if you did my only advice through here would be
rebuild map reboot pc and see if it woorks because if you are like me map might work after you do this but first check out the debugs of tool and game debug to see what might be not working

is the scenario set to be singleplayer or multiplayer in the scenario tag?

It's set to multiplayer.Halo CE doesn't record errors in the debug file,by the way.

make 16 spawn points and have them set to all game types, then try loading your map using different game types. id start with slayer, then ctf, etc. until it doesn't exception. the gametype can cause exceptions a lot of the time

I've tried placing only 2 spawn points before.It worked just fine BEFORE.

Check your globals to make sure you have EXACTLY 6 slots for vehicles, 16 for weapons, etc. An empty slot that isnt sourced to a tag, and appears as 0_Tag_blahblah, 1_Tag_Blahblah, etc. counts as well. If you have more/less than the limit, the map will exception.

1:open sapien
2:select mission
3:go to properties window
4:change map type to multi-player
5:save and rebuild map
5:...Come back and tell me if it worked.
6:notice that i put two 5's....Lol.

...

You are joking,right?

try to delete a Actor variant this happened to me often and it was a corrupted or unreadeable part of the ai in the map file if it doesnt work contact me on xfire

I found the true problem.I had deleted the sound scenery in the map.Apparently,it needs them to function.And my total weapon count in the globals was under 16.
