All computer programs are buggy, including very serious and well tested software. NASA spacecraft MARINER 1 (to Venus) was destoyed due to a software bug.
http://en.wikipedia.org/wiki/Computer_bugYouPlay cannot be perfect, otherwise serious software companies will be disappointed

... therefore we spread some bugs here and there....
Having said that, if you find a bug you should provide us the following information:
link to the game
the TURN NUMBER your are playing (we could check the game sometimes later)
what happened (specify the ship(s))
what you did expect to happen and did not
your decision to suspend that game or not (if you continue will be more difficult to backtrace the bug / if you suspend it feel free to send an email to postmaster@youplay.it and to me, just to be sure we are not sleeping....)
why you do think it's important to fix the bug.
This level of boring details will help us to assess the situation....
thanks ciao Ale
