So I have a very small private server that I run off of my PC. I have about 1-4 people on it. Most of the time just me and my one other friend. We tried to make Redstone build such as an afk sand filler for the ocean thing. Now all the Redstone is correct but it keeps breaking for some reason. I have noticed that there are many ghost blocks and pistons will constantly break as in not move blocks. The slime won't move the blocks because it glitches out or something and moves at the wrong time like its delayed or something and breaks. I have noticed that the lag is mostly in Redstone stuff but every now and again the server stutters. Now I don't have anything reader thing in the console so that's no help. I would like to know why it lags and how I can fix it. I have 4GB on the run.bat file so I think that's good IDK. Any other help would be greatly appreciated! Thanks!
