Map is not broken.

Did you check to be sure your command line has the correct information? Map mod id and name?

Would be good to post your command line here, without passwords to let others help you

-MapModID=661564024?listen?MaxPlayers=60?Port=PRIVATE?QueryPort=Private?RCONPort=PRIVATE?RCONEnabled=True?MultiHome=66.70.227.14?AllowAnyoneBabyImprintCuddle=true?AllowFlyingStaminaRecovery=true?CrossARKAllowForeignDinoDownloads=true?ForceAllStructureLocking=true?NonPermanentDiseases=true?OverrideStructurePlatformPrevention=true?PreventDiseases=true?PreventOfflinePvP=true?PreventSpawnAnimations=true?PvEAllowStructuresAtSupplyDrops=true?TribeLogDestroyedEnemyStructures=true?OverrideOfficialDifficulty=6.67?OxygenSwimSpeedStatMultiplier=15 -server -automanagedmods -log -NoTransferFromFiltering -clusterid=a81aef050c -ForceAllowCaveFlyers -ServerRCONOutputTribeLogs -servergamelog -servergamelogincludetribelogs -vday

Can tell you it's already broken

And How???? An explaination would be good to post along with that...And the "Private" stuff, i put over just for this post. Not giving out all my port info lol.

Not sure if this matters but even single player have a session name. That's missing. Put MapModId=661564024 at the end.
Replace it with ShigoIslands
Make absolutely sure you have No spaces anywhere but in your session name. If you don't have one or doesn't need one, still NO spaces

You using host provider?

I do not manage the Command line. The server host does. And i know for a fact that every other map out there does this exact same thing. This is just a copy off of the command line preview they offer. I did replace the MapModid witht he shigo islands mod ID as i have since changed back to another map, but i know for a fact, it DID have the correct mod id for it.

Arkservers.io. They work great, and have never ever had a problem with anything.

This is an example of my server awhile back. I would replace TheIsland with ShigoIslands and put ?MapModId=661564024 at the end

TheIsland?Multihome=XX.XX.XXX.XXX?Port=XXXXX?QueryPort=XXXXX?SessionName=Misty Mountains?MaxPlayers=20?listen?ServerPassword=?ServerAdminPassword=XXXXXXX?RCONEnabled=True?RCONPort=XXXXX?AltSaveDirectoryName=SavedArk22522?GameModIDs=764755314,893404454,899250777,1215162599?OverrideOfficialDifficulty=6.0

The mod id is correct. You must have the map name load first, always

Then why does this exact same setup allways work on every other single map out there.....Exact same setup.

The setup i posted, is for my current server which BTW is running and i am playing on as we speak, using map Olympus. I just added the map id for Shigo instead of the current onlympus. So....yeah.

If they way you have it isn't working for this map, then change it to that format for this map. I've only been with two providers but all the support you can find says the same thing I pasted. Map name first, mapmodid doesnt even have to be at the end, just a suggestion but I will bet you that format will work for any map out there. If it doesn't, then I would contact the host provider and see what format to follow. They might have a different way with a different map. And seems odd you don't have access to the command line.
Just try it and see. Other than that. i would contact Arkservers. Map may not have been installed correctly on server. But I can assure you, Exilogs map works.

Hello, so as i can read her the only problem comes from Servers hosted @ Arkservers.io - I will try to get in touch with them to provide a fix

Got an Answer from the Arkserver.io Team and they found the Problem.
Please change your Startup Line from :

ShooterGameServer -MapModID=661564024?listen?MaxPlayers=60?Port=PRIVATE?...

To:

ShooterGameServer Shigoislands?listen?MaxPlayers=60?Port=PRIVATE?...
