This script is absolutely phenomenal, and although it has a potential death loop on floor three, I'm still going to give it 5/5 because it's updated so often and I feel like the DEV will fix this issue.
Death Loop:

During this obstacle, you have a 2-part flame phase (10 Steps total, First 6 Flames, then Last 6 Flames). During this, the player needs to stand on row 4 until the second 6 flames go out. The problem is that on occasion, the bot will miscalculate and you will end up in a death loop where it will continuously keep running into row 4 just before the first 6 flames light up. Thereby sending you back to the beginning of the challenge, only to burn again and again. You manually have to override this in order for the script to work again properly. Generally only happens every 9-12 rounds, but with that being said, I've also gone 30 rounds without it doing it. I've noticed it doing it far more since Jagex did their planned maintenance. Possible update to their bot detection system?
Another issue I've noticed is while looting crates on any chest that has the braziers, it "can" get stuck on an infinite loop trying to walk through the Holy Barrier. It will click on the barrier, then before it finishes the action it will click on it again causing it to walk through it again. Then the cycle restarts. This also seemingly started after the JaGeX's scheduled maintenance.
Finally, not a bug, but a failure in the script itself. It doesn't alch anything. I have the items listed, but it won't alch them.
