Replay Mod Forums

( I'm french, sorry if you don't understand all what I'm saying. )

Hello,
I've tried to create my own modded Minecraft Launcher and I want to put ReplayMod for do my timelapse and other thinks. But when I have launch my game, it stop loading and say me the Replay mod is 2 times on the mod directory ( He was only 1 time ). Do you know the problem and do you have a patch ?

I've tried use a old version ( I use 1.12.2 ) of the mod, but the same problem appear.

Thanks for you're answer.

Could you send a screenshot of your mods folder?

Obviously :

Please post the contents of the fml-client-latest.log file inside the logs folder inside your .minecraft folder to some pastebin site and link to the post here.

Note that this log will only contain information on the last time you started Minecraft, not any previous runs.

There is no fml-client-latest.log on the logs directory, only the normal log file that contain this : https://pastebin.com/HZNCnQQu
I precise my Launcher is not the official, this is one I'm coding and he can be missing a librairies or a argument is the launch command line.

How are you calling MC? It seems like Forge is loading the mod from two different locations which are actually the same location, once via an absolute path and once via a relative one. You might have configured the path to Forge's mods folder manually but Forge has also added ".minecraft/mods" to it (which in your case are the same file but forge doesn't seem to realize).

On the launcher, The command is use with Python subprocess.Popen, but I don't think this will help you, the command line is on this pastebin : https://pastebin.com/31BgAkHN ( Token censured ).

I have do the same conclusion than you, but why only the ReplayMod ? This is strange...

I suspect it might be the Mixin framework we're using. Try loading this mod instead, it also uses Mixin: https://i.johni0702.de/betterportals-0.1.jar (don't try to load any worlds, it'll probably crash).

The same problem appear

You probably want to ask the Mixin guys then: https://github.com/SpongePowered/Mixin/
There is issue #253 which produces the same duplicate mod error but allegedly only on server installations, so not sure if it's related. To check, try using an older forge build e.g. 2655.
