EGP/wiring Errors

[nonstopjoker]

Describe the bug
I've been working on an EGP screen, it has text, boxes, and buttons. When I spawned it today (with adv dupe 2), the screen showed the EGP logo with the red cogwheel, normally it shows the EGP right away, so I refreshed it and it was showing the EGP objects, but it didn't look right so I tried egpClear, and it looked more messed up (positioning and scaling was off) even after removing egpClear. Then I spawned a new screen entity and it wasn't working at all. I'm getting two different script errors, I know at least one is from when I select the EGP:wirelink input on the E2.

Script errors I'm getting (couldn't get the formatting to work, sorry):

To Reproduce
Steps to reproduce the behavior:

1. Spawn E2 and a EGP screen
2. Wire E2 to screen with the wirelink input
3. maybe egpClear and refresh?

Expected behavior
The EGP objects should be shown on the screen it's wired to. Sometimes I have to refresh it for it to scale to the screen properly (probably the way I've made it), and it shouldn't give errors.
