[Tough Guy]

I agree that it can be hard to interpret without seeing facial expressions.


However....

"Drain-3 anyone ?" That comment clearly is meant to embarrass.

"Do you really think we wouldn't have spotted an error like this in the last 2 years? " It is clear from the sarcasm that he believes the questions should not have been asked and that the asker is an idiot.

The correct answer would have been:
"Drain -3 causes this. Glad to be of help!"

Sorry to have inconvenienced anyone but I did not appreciate the sarcasm. I believe that most people on this forum not only know the game well but are eager to help others learn it without putting them down in any way.
