    Inside the map, mobs like horses, pigs, sheep and chickens disappear even if they are tied to fences. I created a new map but the same thing happened. I'm playing in Bedrock server

    Changed the title of the thread from “Crash Report” to “Crash Report (mobs disappear)”.

    This has been happening to me as well.

    Losing villagers, minecarts and a bunch of other things all the time.


    Did you ever get a solution for this?

    Aternos User: Aurux Software: Bedrock 1.14.1.4

    Log: https://mclo.gs/MArUhQm

    I have reinstalled the server many times in my old Aternos account, in the new one and in my friend's server and it continues generating the crash report when the server is turned off and the mobs continue to disappear.

    Roman,


    I agree this looks like a problem with BDS itself.

    I've been experimenting with a local server on my own PC and it happens there as well.

    So, yes, not an Aternos issue.

    However, going over the crash report it looks like it fails while writing world data.

    So I've found a workaround which CAN be implemented on Aternos's end.


    before stopping the server run the following:


    save hold

    save query (run a few times until response)

    save resume


    this forces the server to complete it's world writing and it can then be safely stopped with:


    stop


    Been doing this for a few days and did not get the crash.

    Note that this will likely only work if all players are disconnected though since any active player will generate more world data to write.
