The issue is chronic tragic and never been dealt with by you or steam, we can’t do it for you!
You can’t even contact steam about it their end of the problem they just blame you, so I will too. Your update system is sub standard and doesn’t work… After updates players have registry issues trying to load in and it blocks them saying “mod needs update”. This is not our problem it’s yours and it need to fixed after years of dealing with it I’m over it. For one… using Gportal you have a 10 minute delay to even get an update, my private server is instant, that’s just lame and you know it. Lately it won’t even update… it just locks you out from the server and forces you to verify and even then it doesn’t work because a player isn’t getting the updates via steam… can you please stop producing DLC’s and fix the current platform or at the very least talk to STEAM, after years of this crap, please do something… .also are we still using the original Unreal Engine… it has never been updated? Why is that?
