Ok so I have been away from EMC for about 2 years due to work and a crappy schedule. Now that I am back I was trying to make a simple 5 block stone generator. I noticed that every so often the lava and water will not update correctly and end up ruining my generator. Is it my PC or is it a problem with server lag that is causing the issue? I am also not using the best internet yet as I am still house hunting and having to stay in a hotel.Any serious responses are welcome, as well as any serious advice.
