Every time you start a bot, it counts as a full hour.. so you started it at 10:36, that takes 0.12 credits.. you started again at 10:37, it counts as a full hour and takes 0.12 credits
Perhaps the ability to request refund automatically if a bot fails to run for more than a minute or two would be nice? I'm getting a lot of "Runemate has lost its bridge" errors on expensive bots and going around asking for refunds is tedious
Although, now I'm watching the bot.. it plays the mini-game just fine until it nears the end of the round where it just clicks in the same location over and over. It says "Activating quick prayers" in the bot UI
