Well hello hce maps and i will like to thank all the people that helped me out with map making (Thanks ally, you're awesome dude) but i can only play the map i made, with a custom made game(with an edited game type)
if i play it with the default slayer or ctf, it says gathering exception data, i will like to know why does this happens, and why doesn't gathering exception data appears when i create a game with an edited game type in that map?

any help will be appreciated

Sound like an error that could come out:
-script
-placement details like allowed in ctf or ctf default
-netgame flags might be messed up

niels is right here dude,when i was on xfire helping you do the sapien i got the impression you were a bit confused about the netgame flags but my internet connection went down and i couldn't get reconnected to the net,sorry about that dude.

defiantly sounds like netgame flags, check the halo editing reference and make sure you've placed all of them.
