Ah, I see my mistake now. I am playing Vanilla, the reason I posted it here, is because it is the only place I could find that had a problem simillar to mine.

Would you be able to show me in the right direction then, not really sure what to do with it. I am not an expert in these kinds of things.

I just noticed I had multiple logs between 20-50gb. I opened one of them and got the following error around 50 times a second: [16:38:03] [main/WARN]: Exception loading entity: m: Loading entity NBT at aii.f(SourceFile:1537) ~[aii.class:?] at aim.a(SourceFile:432) ~[aim.class:?] at aim$$Lambda$2017/2140749909.accept(Unknown Source) ~[?:?] at p.a(SourceFile:327) ~[p.class:?] at aim.a(SourceFile:431) ~[aim.class:?] at aim.b(SourceFile:484) [aim.class:?] at aim.a(SourceFile:465) [aim.class:?] at bgp.d(SourceFile:250) [bgp.class:?] at dmw.a(SourceFile:20) [dmw.class:?] at dmw.a(SourceFile:15) [dmw.class:?] at dmw.a(SourceFile:10) [dmw.class:?] at dml.a(TileEntityRendererDispatcher.java:201) [dml.class:?] at dml.a(TileEntityRendererDispatcher.java:154) [dml.class:?] at dko.a(WorldRenderer.java:1014) [dko.class:?] at dkk.b(GameRenderer.java:1234) [dkk.class:?] at dkk.a(GameRenderer.java:1059) [dkk.class:?] at dkk.a(GameRenderer.java:798) [dkk.class:?] at cvk.e(SourceFile:954) [cvk.class:?] at cvk.b(SourceFile:411) [cvk.class:?] at net.minecraft.client.main.Main.main(SourceFile:154) [Main.class:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_51] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[?:1.8.0_51] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_51] at java.lang.reflect.Method.invoke(Method.java:497) ~[?:1.8.0_51] at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) [launchwrapper-1.12.jar:?] at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.12.jar:?] Caused by: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $ at com.google.gson.internal.Streams.parse(Streams.java:60) ~[Streams.class:?] at com.google.gson.internal.bind.TreeTypeAdapter.read(TreeTypeAdapter.java:65) ~[TreeTypeAdapter.class:?] at zm.a(SourceFile:493) ~[zm.class:?] at zm.a(SourceFile:518) ~[zm.class:?] at jm$a.a(SourceFile:393) ~[jm$a.class:?] at aii.f(SourceFile:1512) ~[aii.class:?] ... 25 more Caused by: com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $ at com.google.gson.stream.JsonReader.syntaxError(JsonReader.java:1559) ~[JsonReader.class:?] at com.google.gson.stream.JsonReader.checkLenient(JsonReader.java:1401) ~[JsonReader.class:?] at com.google.gson.stream.JsonReader.isLiteral(JsonReader.java:751) ~[JsonReader.class:?] at com.google.gson.stream.JsonReader.peekNumber(JsonReader.java:706) ~[JsonReader.class:?] at com.google.gson.stream.JsonReader.doPeek(JsonReader.java:584) ~[JsonReader.class:?] at com.google.gson.stream.JsonReader.peek(JsonReader.java:425) ~[JsonReader.class:?] at com.google.gson.internal.Streams.parse(Streams.java:46) ~[Streams.class:?] at com.google.gson.internal.bind.TreeTypeAdapter.read(TreeTypeAdapter.java:65) ~[TreeTypeAdapter.class:?] at zm.a(SourceFile:493) ~[zm.class:?] at zm.a(SourceFile:518) ~[zm.class:?] at jm$a.a(SourceFile:393) ~[jm$a.class:?] at aii.f(SourceFile:1512) ~[aii.class:?] ... 25 more Please do say if I should add more information, as I have no idea.
