Big assemblies specifically welded only crashing ingame

Since november last year big creations in my game have been crashing when unanchored if 2 parts with tons of parts welded to eachother are connected with eachother via a single weld.

This is making it impossible for players to play my game properly because as soon as they launch their creation their games crash.

I have been working closely with someone to get it fixed but its only been fixed in studio so far but it still crashes ingame.

Game affected: 🔨Plane Crazy🔨 [UPDATE] - Roblox
