So I was playing CTF today, and I observed that whoever of my team took the flag was falling into the void even though i personally was at the only Parkour and ensures they crossed it safely. When I went back to base I saw that one of my teammates had dug out a moat around the flag into the void. I thought it was for safety, and I was making a bridge for the incoming flag, but that teammate mined the block exactly under me and I fell into the void. How was she able to mine blocks under her own teammates?? It wasn't possible before.
