Minecraft crashes with v55 and 54 when paired with Dynamic Surroundings - but v1.0.3-48 works fine. There seems to be a problem with mixin and maybe it's just Dynamic Surroundings that is not up to date, or causing the issue...

Here's the log: https://pastebin.com/U5cEFTsp

Same here

DynamicSurroundings has updated, and Agentwolf is using an outdated MalisisCore.

MalisisCore is not the problem.

It was one of the issues, update your mods. VanillaFix isn't even at the latest and I doubt Phosphor is either, so this is more user negligence and not keeping mods updated
