The buddy bots have NEVER been known for their support/update speed with errors. They've simply been known to blame the customer saying its the issue between the computer and the chair, so sorry complaining like this will get you nowhere.
Time to be helpful...
Anyways, to clarify a bit of personal experience, the bot works better when only a single instance is running. See the vm guide to make multiple "single" instances and your issues will be almost nil. Doing this on 4 vms for 8 hours I had only 2 crashes, which were of d3, other than the nbulous stucks i had to fix (but a good inactivity timer fixes that if youre less impatient than i).
As for the login issue, spam the login button as long as it doesnt say max sessions, works for me every time!
