No, it actually becomes less rng based. I make a path tile by tile, add every interaction manually without using DreamBot's A* algorithm. But even then... there's still the chance that the bot will run into the issue. For example I haven't seen it getting stuck at Tenzing's gate in months, but it still can get stuck at Regath's house (depends on the loaded map chunk). Sadly there's not much that I can do about it. DreamBot's algorithm is very unstable, it has no timeouts when interacting, heavily relies on the loaded map chunk. It sometimes thinks that a door is preventing the bot from reaching next tile and starts spam clicking on it. Let's hope that DreamBot is going to improve walking in the upcoming DB3.
Please be more detailed or at least take a screenshot. It's a quester, it requires 1 account to test the quest 1 time. I tested the new version on 5 accounts (all the mentioned quests) and haven't seen any bugs. Hazelmere's ladder is already hardcoded, I'm not sure if there's something I can do at this point if there's still a chance for it to get stuck. Check my previous reply for more information.
