This bot is totally cracked, and the author is amazing. 11/10 would recommend <3
Anyone claiming that this bot is "red flagged" is a fool. They definitely banned for other reasons (like using other/worse bots/suicide botting/etc). How do I know this? Well, I just botted 1,150cg kc on my main in ~90 days, have waited several days, and my account doesn't have any ban of any kind. If I didn't get flagged as a bot in the 200+ hours of cg botting I did, then this bot clearly isn't red flagged.
Often these kinds of issues can be fixed by restarting OSRS & Runemate (or your PC). Also make sure to disable any plugins which may be interfering with the bot.
Feel free to test using the lite version so you don't get charged, and let me know if the issue persists.
