The biggest problem in Tactics is that it is impossible to know which side White began from. Sometimes White begins from the top, sometimes from the bottom. The only way to know for sure is through an educated guess, but that does not work out in all cases.
The second biggest problem in Tactics is that some problems are intolerant of alternative correct answers, or actually promote the wrong answer over the right answer. There are not many problems like this, but there are some problems like this, and no way to report them. I have commented on the bad ones because commenting was the only thing I could do.
Unless you have your settings to always show white on the bottom, the side to move is always heading up the board; i.e. the board is correctly oriented for the side to move.
Which side is up?
