URGENT FIXES NEEDED

[physicshub]

Hey guys, important message here, this is the announcement from Discord:

URGENT FIXES NEEDED:

I've been working on a completely new and improved simulation system for a few weeks now. It's more centralized and beautiful.

This was also one of the reasons I delayed the reviews. Now I've pushed it, so I'll be able to see your PRs.

**The problem is that I pushed it in a hurry, so it has a lot of bugs, so it's not in production yet.

PLEASE TAKE A LOOK AT THE NEW BUGS (especially in npm run preview) AND FIX THEM.**

I'd be very grateful.
