People trying to work the problem.
Sometimes being open to possibilities is how we find solutions to problems that crop up in a wide variety of software. Computers are funny about interactions. Sometimes what appears very complex turns out to be something very simple. Usually that simple solution is stumbled upon by spit-balling ideas.
I have been witness to far too many simple solutions involving users own systems. If everyone is experiencing the same thing then I am the first one to agree on a bug. When I see something that affects a relative handful of users I tend toward determining why not everyone. Very few bugs are random. They are usually repeatable when the source is found. Random errors are usually user related in some way. Asobo is NOT going to waste on computer cycle on finding solutions to user effects. It falls to the community to solve those errors.
Try to keep an open mind and you may find the “buggy” sim isn’t as buggy as you think.
