Describe the bug
A clear and concise description of what the bug is.
Server and client crash at launch with the mod installed. I know Supplementaries is also there, but I don't think there is a link ? I already posted an issue for that mod.
debug.log + crash report : https://gist.github.com/Daltaxy/cac1323e0e53e7f7c5352634e8836b11
To Reproduce
Steps to reproduce the behavior:
Start the game with the mod installed. Yesterday everything was fine so it is either due to forge, or elementalcraft, which had an update yesterday. Note that reverting back to the older (the one before the latest) version of ElementalCraft did not fix the issue.

Expected behavior
A clear and concise description of what you expected to happen.
no crash; everything worked fine yesterday
ModPack
Either a known pack (ex: ATM6) or a Twitch/MultiMC export
own mod selection

org.spongepowered.asm.mixin.throwables.MixinApplyError: Mixin [ae2ao.mixins.json:PlayerListMixin] from phase [DEFAULT] in config [ae2ao.mixins.json] FAILED during APPLY

ae2ao mixins seems to be broken. there is a good chance this is the cause.

thank you. I'm sorry. I have no idea why the logs, at first sight, indicate these mods.
Anyways, yeah, removing it fixed the problem. thank you again
