If you make arrows you get 5 then if you go ahead and make more you create an arrow that stops halfway through on its own. If you then move that arrow to another slot you can finish it and get another 5 arrows. However the 5 arrows that were under that are now 50% done as well meaning you only need to finish them with thread. This means that wood is taken out of the formula for arrows in return for 1/5 more thread.
Just to prevent forum spamming. The staff therefore implemented this possibility to report bugs. So why not use it? There is a reason that it exists for sure.
Yes it bothers me.
You've done the same thing to me twice. Once in the proposal, and once in the off-topic.
From experience, bugs reported directly to staff members (through the forum or on MSN) are fixed 10 times faster than the ones reported on flyspray.
