#2114 compiler ignores parenthesis important for order of execution

The compiler doesn't seem to be able to determine, whether parenthesis are important for the order of execution in a chain of statements. a || (b && c) && d && e && f is not the same as a || b && c && d && e && f The specific line I was using is if(this.autosaveTimer == 0 || (this.director.state == "pause" && == "dungeon") && this.director.player.tutorialState == "Ended" && dungeon != 5 && dungeon != 7) I tried swapping the part in parenthesis with the first part, but that still gives a wrong result, with the parenthesis removed. I'm pretty sure I have seen the parenthesis work in other contexts, at least in numerical operations, but I'm not entirely sure. > What version of the product are you using? Is it "nightly build"?

I don't think the specific file is of much relevance, but if it would be helpful, I can provide it
Logical or operator || has lower precedence than logical and && operator. This means a || (b && c) && d && e && f is equal to a || (b && c && d && e && f) and that is equal to a || b && c && d && e && f as && part is calculated calculated first. if you want to make a || (b && c) first, then you need to use parenthesis this way: (a || (b && c)) && d && e && f
