Hi gang!One problem which I came across in-game quite a few times (even before I started experimenting with mods myself) is: "Help, my chests are invisible!". I noticed this happening on a few servers; I went over to the players plot and saw the chests just fine (on vanilla; MC 1.8.4). Obvious conclusion: its not server sided, so it has to be their setup. Talking things over learned me that players were using mods and so far disabling Optifine worked for them.In case you're wondering what I'm talking about, this:There are chests there, see outlines + item frames...Before you wonder: I know that disabling Optifine is overkill and that relogging might also have fixed the problem. Keep in mind: when I tried to help these players all I knew was that Optifine was a plugin which enhanced graphics. That's all. That has changed in the mean time..So when this happened to me I was all the more eager to find a solution. And I think I did come up with something which doesn't even require you to relog:Open the pause screen (escape) & click "Options".In the Options screen select "Video Settings..."In the Video Settings screen select "Details..."Focus on the option "Translucent blocks..."; remember what setting you're using now.Click this option until you get the previous setting again.Done.Changing that setting works "on the fly", in other words: it becomes active right away. I tried this option because I figured that the invisibility was some kind of translucency. And well, for me this got the chests visible without disabling or reclogging:Bingo; problems fixed.Hope this can help some of you guys.This is not a specific EMC problem: its Optifine having a glitch.
