As far as i know there was only one incidient... a paintball came over field 4 and into the xball team area, hitting someone just above the eye, however when they left i believe that had blindness in the eye, so wait for more confirmation on it!! All my hope goes out to the guy, not what paintball needs!!
Apart from that there was no rain but it was the glasto of paintball, the safe are and trade area were deep in mood and most of the fields had there fair share of puddles and still water...
Markie i dont know exactly how the firm did but i dont think it was first, but i will stand to be corrected
