So, after having looked at the problem with closer scrutiny, it seems that the bot believes that it has already left the arcade on the very first attempt, so the status changes from "Exiting arcade" to "entering arcade", hence it doesn't make an attempt to exit it again, because it concurs that it has already done so. But as soon as it dies, it reenters fine. And I would like to acknowledge another bug fix, thanks to this upgrade. Earlier, the bot would sometimes just sit there, rather than trying to enter the arcade, but now it does so every time, so thanks for that!
Lord, although I believe, and after having thought hard on it, it could well be a problem from my side, I am just running too many of your's and @EmmaStone artistically crafted bots. XD! And coming to the potions parts, a support for restore potions, and mage/range potions would be lovely. And as you may already be aware of, there's a bug which has turned some of the creeps into super creeps, unintentionally, as they say, making it quite hard to progress beyond certain stages. So I reckon that you could hold on further developments till that is resolved, and take some well-deserved rest!
