1. Guest, as per the stickied thread, this forum has not been in use since 2014. All bugs and feature requests should be posted to JIRA.

Possible bug, videos included. Buttons & Signs falling off wall on chunk boundaries.

  1. I want to preface by saying I realize this might not be a spigot bug I have not troubleshooted (shot? haha) properly. Normally the procedure is to disable all plugins and reproduce, but I have world-guard related no-decay flags (among others) that will really mess up some of these builds if things are allowed to suddenly decay. Is there a safe way I can test this?
    Note: It isn't super feasible for me to download everything from my server to my pc, but I will if it's the only way.

    Java: Sun Java 8u45 (also happened with 8u20)

    Here is what I'm experiencing:

    This is only happening in one very specific place and it only happens when I load certain chunks in a certain order and the effect is repeatable, but only in this one area, I cannot reproduce it anywhere else.

    What it involves:
    1. Chuck loading
    2. Buttons and Signs (but only when placed adjacently)
    3. Command block

    So I created some videos because it's hard to explain.

    Video #1:
    http://www.twitch.tv/malonnnn/b/655945593

    In this video, I demonstrate that pushing the button with a sign above it (does not have to be above, just adjacent) warps me to spawn. Then I "/warp rulehall" and zig-zag down the hallway to find the buttons and signs on the ground.

    Video #2.
    http://www.twitch.tv/malonnnn/b/655946082

    The video has 2 demonstrations. First, instead of zig-zagging, I dig through the ceiling and take a straight path to the button and sign. They are still on the wall. Apparently it's related to the zig-zagging. Second I perform the same actions as Video #1 so that you can see the zig-zagging causes it to happen again.

    Video #3.
    http://www.twitch.tv/malonnnn/b/655946455

    Same as video #1, but instead of pushing the button, I manually "/spawn" myself, then "/warp rulehall" to find that the issue did NOT occur. It's now apparently related to zig-zagging AND using the command block.

    Video #4:
    http://www.twitch.tv/malonnnn/b/655947435

    This contains 2 examples. The first is that using torches and 1 button the issue did NOT occur. I then proceed to break 1 torch, replace it with a sign, and the issue occurs again.
