Replay Mod Forums

I installed replay mod yesterday. At the beginning everything went well, then after a while my replays began crashing randomly. I can stay between 10 seconds and 3 minutes and then it's as if chunk unload. However, the game does not crash and I stay in the void. An image will be more explicit : https://imgur.com/nIW2SwI
As the game did not crash, I have no crash report and I specify that there is no other installed mod.
my configuration : window 7 x64 minecraft 1.12.2 replay mod : 1.12.2-2.1.3 forge : 1.12.2-14.23.4.2705 java : 1.8.0_51 64 bit
Thank you in advance for your help and sorry for my bad English

This is a know issue which I'm no longer able to reproduce. I've uploaded a debug version of the mod which will print valuable debugging info when the error occurs but everyone who I've previously asked to run it has either seemed to ignore me or disappeared never to be seen again. So if you could run that version and give me the `fml-client-latest.log` file after it crashes, that'd be highly appreciated. https://www.replaymod.com/forum/thread/2097#post9315

Contrary to the last version of the replay mod which prevented me from making render even before the crash, this version allowed it me.
Here is the fml client latest log : [spoiler="[16:17:26] [main/DEBUG] [FML/]: Injecting tracing printstreams for STDOUT/STDERR.

You're trying to load the 1.7.10 version of CodeChickenCore on 1.10.2 MC.

I used the 1.7.10 version Code chicken Core but But I deleted it since

Maybe you've got the wrong log file then. Try clearing out the logs folder before starting MC to see which files are the relevant one.

I have 5 zipped debug log and a file in a text format. What's the right ?

Let's try the text one first.

the first zipped debug log : https://paste.replaymod.com/xumebafude

That file has the right amount of debugging information and shows you rendering something but it doesn't seem to contain the crash.

I think this file is the right but it make approximately 1150ko

No, sorry, seems like no crash in there either. In the launcher (in the old one anyway, for the new one they for some reason decided to make this more difficult; in that case Google is your friend) there should be a "Game Output" tab which should also contain the log of the game (there's less debugging info there but it should still be sufficient and hopefully complete).

I looked in all the files of minecraft but I dont know where I could find logs more complete.
I have a question : Why this bug arrives it only at some people and not at everybody.
