Economy reset 10 days before the launch of GTA VI.
Bring more people back in the server and make sure they spend much time to help the server be alive.
Development in SAES servers has always been and will always be slow, passive and full of criticism, as a player who has been around for more than 15 years I can see a big issue on all of these problems you are now willing to fix. The big question is "Is it too late now?"
Players wanted the GTA V SAES server since 2018, the SAES SA 2.0 ended up being a meme instead of a huge update and the biggest problem was the same. People always had been promoted by their status and their personal relations with admins and players with power.
This server is suffering from all this and as for the communication problem it's a big toxic place where everyone's treating his teammates as a garbage bin.
I'm just saying my personal opinion since I've quitted the discord servers because it's not a safe space for normal conversations.
We all wanted this server to thrive and have fun when we come online to play and I am thinking that a hard reset won't fix any of that, some names will replace the old ones that "abused" the economy, the system etc.
Good luck with your new plans and I will come once in a while to say hello.
