Ahahahah no worries, happens to me all the time! :)

I stopped any actual investing apart from specific cards, its impossible to follow this line of play unless you don't know what to do with your money; especially given the fact your cards are almost unplayable after a couple of sets unless you enjoy playing bots. Will keep trying to upgrade the most useful cards for me, and that's it.

Hope to face you in human format soon, even if it is in a survival mode! ;)
