Tinkers Construct warning

[Sereath]

Describe the bug

Log notified me about:

[Client thread/WARN] [Alfheim]: Something (likely another mod) has attempted to modify the world's state from the wrong thread!
This is *bad practice* and can cause severe issues in your game.
Alfheim has done as best as it can to mitigate this violation, but it may negatively impact performance or introduce stalls.
In a future release, this violation may result in a hard crash instead of the current soft warning.
You should report this issue to our issue tracker with the following stacktrace information.

You should report this issue to our issue tracker with the following stacktrace information.

Why, why is that a thing?

Pretty sure this is on the mods side to fix, I will still take a look anyway.

It looks like Tinkers' can leak the server's world to the client because it spawns particles via its Proxy classes improperly. See CommonProxy and ClientProxy.
It's easily reproduceable with just Tinkers + Alfheim (and related dependencies): just get any Tinkers' weapon, apply the Fiery modifier with blaze powder in a tool forge, and start hitting mobs with it.
Might be something for Universal Tweaks to fix.

Thank you both for checking. Yeah, I also had a tinker's longsword equipped, I believe, I noticed this warning about 5+ times when I was testing stuff in a new world.
