while it's possible for players to join during a mission, this is discouraged during setup because it can break some functions when the player count changes during execution of mission generation, calculating positions of spawn locations, et c. either join the mission at the beginning or when the mission is fully generated and players are just waiting at the initial start position (FOB).

@Elite911
set up your dedicated server with the correct configuration and either customize the missions class in server config or empty the class to be prompted for mission select. be sure that the desired mission pbo is in the mpmissions directory and it should appear on the mission select pane for whatever map it is (altis, et c). then when you start that mission it will begin in the lobby and you can set mission parameters and other players can join. it is very important that whoever is in control of the mission take the 1st player slot. otherwise it is also safe to just start the mission with one player, make sure that you have the mission options, and then have other players join you before the mission is generated.

How do we start a new game on a dedicated server and how can my friend and I join in the same squad?

that can sometimes happen if a player joins during the mission generation process. then there is a mismatch between the expected number of players (before "start" is clicked) and the actual number of players (team planning area). it's a JIP issue when a player joins in the middle of a script executing, unfortunately. the safest bet is to have everyone in the lobby before the mission starts, or have everyone join after the 1st player starts the mission and sets the objectives but before the "start" button is pressed.

Tried using this mission on our dedicated server last night with ACE and some other mods loaded, everything was working fine until we finished our loadouts. Once we all went back to team planning and hit ready up, no insertion ever occured. No players showed in the team planner, and we were stuck at the base and had to run 5km to the nearest objective.

@Brenner650
HALO mission start has no FOB. are you using any other mods besides CBA and ACE? have you tried resetting the mission settings to default from the main menu before generating the mission?

Also if random deployment type uses halo jump, you don't get a parachute, and crush to the ground, which makes you respawn in the lower left corner of the map.
And there is no FOB. (not sure if that is how it's supposed to be)

@Brenner650
be sure that are have ACE properly configured and are not using strange settings or other mods that can intercept or modify hit events. be sure that "revive" is disabled if using ACE medical, or enabled if you are not using ACE medical.

the error is related to the map location not having enough space to spawn vehicles or their respawn location due to the requirement for flat terrain relatively free of obstacles. it shouldn't hurt the mission itself, only some things will not be present at the FOB. this is map-specific by location and happens mostly with custom chosen positions. i've updated the mission a while ago to remove some types of locations as valid mission locations but maybe on some maps a valid location is still too cluttered or not flat enough.

thanks for the update, however I do not receive any damage from enemy shots (I do get falling damage, so its not a god mode, but enemy soldiers cannot damage, or kill me), and got this in my RPT:

Error in expression <cation < 3) then {

Hi, thank you for your effort, did you by any chance managed to check the error I posted in discussions?
Is there a discord we could talk about it in real time?
Thanks
