Can confirm, definitely not the only one. I ONLY get disconnected when rebornbuddy is working. Its annoying b/c I cannot afk. I am getting this while fishing as well, so it's just not combat. I'm using the 1-50 fishing profile through orderbot.
Consider your Firewall too. I know when I last experienced constant 9002 errors it was because of ESET Smart Security blocking all the server requests for the authentication and game servers. Either port forward on a static IP or put the game into your firewalls whitelist. Ofc this does not guarantee a solve, I've also noticed it block a few other IPs (I'm guessing they're backup servers on SEs end) that are blocking the games access. Luckily I'm using the beta of SS9 so I can whitelist common blocked events from the game straight from the main ui and with permanent rules. Since I've done all the above, not a single disconnect.... Sure, SE servers might have probs, your ISP may be being a dick. But before all that. Check your own hardware/software.
