Not true, most of well coded Simba scripts have enough fail-safes to make it impossible to go to a completely different place, and if it gets lost, it will log out and not start walking to any place. The messups vary from script to script, but a good one doesn't messup. I remember my draynor willow chopper and banker, it was flawless and could run endlessly but the only problem was the randoms that SRL could not solve though it didn't happen often. Since and before the bot nuke, Simba has always been my favorite bot. Why? Because it's a color based bot and the SRL incude makes the scripts to work like humans do, looking at the screen and making a decision based on what it saw, not like reflection and injection bots who already know what's on the runescape client without looking at the information in-game...
