AHAHHA LOL!!!! Haven't tested the bomb setting off mines yet but since you did, I'm sure it's fine, HOWEVER you inadverntatnly opened up an exploit for spawn killing.
Apparently when you call for the mines to be removed at the round end, you are able to place mines again immediately after your original set disappears. I did this on ka_needle and allowed me to spawn kill the entire opposing team with a few strategically placed mines.
Was funny but I had to disabled demolition man again for now. HAha...still laughing.
