Strictly follow depth chart means exactly that, but in-game events can affect the settings (fouls, injuries, blow-outs).
Regarding other bugs, I have no intention of arguing with you and jumping from one bug to another. We have a list of known bugs as a sticky in this forum, so I'm not going to repeat that.
As for GE bugs in general, I've already said that we will soon be able to work on them. Since it is a very complex part of the game that needs lots of dev time, some very specific resources and extensive testing, I really can't say when exactly that will happen, but I believe it is in the foreseeable future.
