IK Plugin and Scrolling Problem

Yeah, so it's pretty sad when I'm having problems with my own plugin. Anyways, I think I might have uncovered a bug in Construct somewhere when using my plugin. The ZIP file below contains a CAP file with the bug and my plugin for those who don't have it.

Some kind of bug

What you see is an IK arm I have set up. It can be moved around with the arrow keys. The problem is with the screen scrolling. Soon after the screen scrolls over, the bottom arm disappears, but once you move back it will reappear. If you turn off scrolling(on the blue square), everything works correctly, no matter where you move.

What's stranger is that the purple rectangle I have positioned to the bottom bone at the same angle will never disappear and stays where it should.

I honestly can't tell if this is a problem with my plugin or Construct. If anybody wants to look at the code to the plugin I can PM it to them.

strange indeed

I created a new project from scratch to see if there was anything random that might have caused it

but it does the same thing

a shame, too

I'm a big fan of the ik plugin

if you'd like to pm me the code I'll take a look and see if I find anything
