nepphhh

This seems to be a bug with SnowRealMagic.

No, I realized that they were two completely unrelated issues. As all the advice in that previous thread was related to the innocuous log spam related to the endermen spawners, not this much nastier issue, I thought it would be appropriate to separate the issues into two different threads. If this isn't what I should do, I will consolidate the threads again. Apologies if there's been a misunderstanding.

I have made a github issue on a repo which attempts to patch this, but I will also put it here because it seems like an issue that would need to be fixed in any modded install. https://github.com/TheRandomLabs/RandomPatches/issues/116 The following exception crashes the game hard, repeatedly, and frequently. [27Jul2020 03:16:30.570] [Server thread/ERROR] [net.minecraft.s erver.MinecraftServer/]: Encountered an unexpected exception net.minecraft.crash.ReportedException: Exception ticking world at net.minecraft.server.MinecraftServer.func_71190_q(MinecraftServer.java:856) ~[?:?] at net.minecraft.server.MinecraftServer.func_71217_p(MinecraftServer.java:788) ~[?:?] at net.minecraft.server.integrated.IntegratedServer.func_71217_p(IntegratedServer.java:81) ~[?:?] at net.minecraft.server.MinecraftServer.func_240802_v_(MinecraftServer.java:643) [?:?] at net.minecraft.server.MinecraftServer.lambda$func_240784_a_$0(MinecraftServer.java:230) [?:?] at net.minecraft.server.MinecraftServer$$Lambda$6550/1020321556.run(Unknown Source) [?:?] at java.lang.Thread.run(Thread.java:745) [?:1.8.0_51] Caused by: java.lang.IllegalStateException: TickNextTick list out of synch at net.minecraft.world.server.ServerTickList.func_205365_a(SourceFile:54) ~[?:?] at net.minecraft.world.server.ServerWorld.func_72835_b(ServerWorld.java:329) ~[?:?] at net.minecraft.server.MinecraftServer.func_71190_q(MinecraftServer.java:852) ~[?:?] ... 6 more Exceptions are accompanied by a brief freeze (sub-1-second) followed by a crash-to-launcher. In my experience, it is more frequent when chunk generation/loading is backlogging server ticks. Examples include fast travel in creative, using /tp commands, and when entering/exiting the Nether in previously ungenerated areas. Prior to recent commits to that repo I linked above (faef98 and a5563c) it seemed to me to arise most frequently in the presence of multiple hostile mobs/mob spawners. Since those commits this behavior is absent and crashes are far less frequent (occur on an hourly basis, not minutely basis). AKA: the "fix" isn't totally a fix, but it helps. I'm not sure--but this seems like something that Forge should take care of. A quick look around shows a lot of people are starting to deal with the same crash recently.

Is there a patch to fix this vanilla bug?

Thanks for the lead. Looks like this is the bug: https://bugs.mojang.com/browse/MC-189565 The crash apparently is completely unrelated to the enderman spawners & is solely a problem with the TickNextTick list out of synch bug. I've been getting repeated crashes without any kind of log spam now for a while.

My game is crashing semi-reproducably during mobs spawning & chunk loading.
