That's not a FC issue, you just have entities that were saved in the wrong chunk, which isn't being influenced by FC and happens in Vanilla too. See the log line above for the relevant message, the stack traces are useless vanilla spam.
Oh is there anyway to identify what entities are causing this? The log didn't say much and this only happens on flat world.
http://files.player.to/fastcraft-1.25.jar should fix the optifine-shaders issue, I can't fully test it with this PC though.
Oh I forgot to return back to the forum after I posted the crash, I'll test it soon, thank you very much!
Meanwhile, I'm having this Log Spam when I tried to test something out by creating a flat world. This spam happens every 20 - 30 seconds though.
I'm just standing still and creating minetweaker scripts, so basically I do nothing in the world and the spam is continuously happening in the log.
I don't know if this is from fastcraft or not, but I mentioned it because the log says fastcraft on it. I'm sorry if it is not.
Edit: the new fastcraft works well with optifine shaders. So far now issue, I hope it will stay that way. And no performance issue as well with 410 mods.
Thank you Player!
Hi there I'm getting crash when near village with shaders from optifine. I can reproduce it, everytime after crash and I relog back in at the same place it will crash me again sometimes not directly, around 5 - 10 seconds sometimes directly.
Here is the crash log https://pastebin.com/DVBYaeeR
I don't know if this is the correct place to report this but the crash report mentioned fastcraft and shaders.
