— Update:
— Laser Tools now have beam length maxed out by default
— Further improvements to welding and pulling code
— Support inventories are now updated in asynchonous fashion, this means that this process no longer occupies the game's main thread -> +40% to performance on average
— Public Debugging mode added (see description)
— Public Performance Debugging mode added
— Asynchronous Welding mode added ( highly experimental and disabled by default , see description on how to enable)

— Update:
— Redesigned pulling code
— Redesigned inventory support code
— Redesigned welding algorithm

Hopefully, the non-welding issue is now resolved. At least, welders now work for me in all test cases (projectors included). They still don't complain properly about missing components, investigating the issue.

— Update:
— Laser tools now refuse to pick up items if their inventories are >75% full.

Still investigating on why the welders sometimes stop working.
