I was playing in my friend's server for weeks now and one time something weird happened. A lot of creepers were spawning on less than 10 blocks close to me, it felt like there was a hacker in our server while my friends thinks that it was because of the server glitch or something. So my friend reinstalled the server and it went normal, however the problem occur again. This was the 2nd time that happen and it almost kill me. Is this a glitch, server lag, hacker? What is it? Can I stop this somehow? Whoever knows the answer, please help me... (sry if my grammar is bad)
Thank you
