On the debug panel i see, that there are 18 functions running
I press mouse, call HighlightAvaivablePath() function, then i call another function that consists of

void PlayerActivate()
{
for first to last node
{
turn
move
}
beep
}

So, player starts moving(i see 19 funtions), pass all path, function beeps and ends(probably), but there are still 19 functions on debug panel

In addition, when i select player again, i get "crash in HighlightAvaivablePath()" that called before PlayerActivate(), BUT if i place breakpoint before them and run it with F10, i see that it crashes at the first line of PlayerActivate()

How to debug this?
