I'm a new RS/RM user and have only limited experience of available bots, BUT imo the Kush Account Builder is definitely going in the right direction. I was happy and yes you need to watch the bot, but was doing most activities well, some poor. But I've seen 3 recent upgrades and definite improvements. My character is growing in the areas I specify, only come across one stumbling block (did no buy arrows!) but Cooking, Magic are working well, just to name a couple of recent activities. Looking forward to seeing how the Kush Account Builder develops :)
2. Did you have enough money in your bank to buy a bulk which will last 3 hours? I think that's going to be around 5-6m to purchase the diamonds, if he have to walk back and forth to buy/sell the items, it's kinda obvious it'll reach shitty experience / hour.
3. How it exactly works is that it'll take randomly the highest activity available, let's say you made some unfinished potions, you should after that just disable the unfinished potions and then it'll work correctly.
4. This never happend to me, I got several account to like +60 thieving this way, so that's something I'll have to look into.
5. It checks for a certain distance if it's worth to use the teleports, apparently you were too close in order to use the teleport, it should only buy like 5-6 as a maximum so I think there is something wrong which I have to check out.
