I have a Gmod Stranded server and everytime i change the map it changes from stranded to sandbox even when i custom switch etc an u guys help me sort this porblem

Have you set sv_defaultgamemode to stranded?

no how do i do that its not a dedi server i bought it on ukgame

Do you have access to TCAdmin?

i have access to everything

Well go to your TCAdmin and look for something like ‘Command Line’. Add +sv_defaultgamemode stranded as one of the options.

already done thats not the problem

Did you ask your hoster they can always help

Maybe sv_defaultgamemode is being set in your configuration files as part of the standard package. Try checking server.cfg/autoexec.cfg for anything gamemode related (These are found in garrysmod/cfg).
