SpringConstraint visualization broken

One attachment is being updated by Roblox physics and the other (the one on the plunger) is being updated via script

You can see when the second time the plunger attaches to the ground, the spring visualization glitches

Its only just the very slightest bit annoying and I would prefer to avoid scripting my own SpringConstraint visualization because it will be just another extra slow lua written piece of code to slow down my game and cause a lot of slowness and lag and make it unplayable for mobile because of its slowness so it will lose me and Roblox money because the market is like what 50% mobile?
