RandomPatches is a direct conflict with Aristois. Please send your log file from when the error occurs

.t IRC-Mute

You can find a list of all the commands here: https://aristois.wiki/features/#C4

It’s not one file that determines the language, and it’s closed-source, so it’s not possible to translate locally.

No

We did reply the same day, so you may have missed it.

If any game tabs or launchers are open during installation it may not have updated the files to load in. Good to hear it’s working now though

I don't understand what you mean by this. Do you mean your config was deleted? Nothing from the config affects the Trajectories mod.

I have the same issue, it is caused by resourcepacks I believe. You can disable all but vanilla from the options.txt

edit: why i believe it is the resourcepacks is because disabling the developer pack stopped this error

When will this bug be fixed?
