I believe riot implemented some "anti-bot" features on this new PVP client. Some functions stop working were should be no reason for that. Result it's that I have to review a lot of the code/script steps and debug were it stucks and try a new method.
Then ofc the old popup messages they are all changed now, so I have again to get them while running to fix them.
Yes the 400rp check it's giving troubles so probably if you disable xpboost it will just run.
I will try to do something while lunching.
Regarding the accs being deleted when you update the bot with a new file, this is something that already happen in the past.
So if you have experience on that, the first thing you should do before update new files of the bot or run new vms it's to save your accalls.txt and put it blank!.
So when the bot starts says No accounts to pull in all, then you just put the accs on the file and click on OK on each bot.
it's not so hard to do it, if you don't know what you runned already and you lost accs, just go to accsused copy paste to accs. if they are already lvl10 the bot should skip and keep going acc by acc.
But for today I suggest you to go "slow". Maybe play with few vms.. Since I will be changing more versions...
