I don't know if this has been discussed before. I searched for it but couldn't find anything. Today I was playing and I was on the mex side, and our team won. The next round I started the same place I was at the end of the round. I could run around without anybody seeing me. I shoot at people but they don't die, but someone was using granades and he could kill people, while he remained as a ghost/invisible. I don't know if anyone noticed this, I hope the developers take notice and fix it in the upcoming patch.
