The Bug
End of texture of powered tripwire hook with string on it is lower than texture of normal string.
Reproduce
Make a tripwire contraption with connected string
Activate it
Observed Result
The string was lower
Expected Result
The string would be at relatively the same height
Can confirm, but it is important to note that this is (as far as I've gathered) only visible when the tripwire is activated by an entity. Meaning this is not the case in its default state.
