How to remove the unnecessary long sound at the beginning of a battle.

Take this file and rename it with the .wav extension, then place it in the data folder; it should work. This is for the start of a new day. For battles, you need to copy this file several times and name it battleXX.wav, where XX should be a number from 00 to 07. I think it works like that. You can also make a copy and name it newweek.wav; then, there won't be any sound at the beginning of the week. Alternatively, you can disable the sounds in the game altogether; then, neither monoliths nor city buildings will take up time.
