Variable displays different value than it actually has.

[Quidney]

Expected Behavior

When I assign a value to a variable, it should display it correctly.

Actual Behavior

It's actual value and displayed value on 'debug'/'display variable' are different.

Steps to Reproduce

HERE'S My project where it happened, because I couldn't reproduce it.

But here's briefly how I discovered it:
I got this problem while creating a 'DeltaTime'.
0- Create variables, "_previousTick", "_currentTick", "DeltaTime", "_deltaTimeClone"
1- Create a callable function, lets call it 'StartLoop'

when I receive "StartLoop"
reset timer
forever
	set _currentTick to timer
	set DeltaTime to (_currentTick - _previousTick)
	set _previousTick to _currentTick
	set _deltaTimeClone to DeltaTime
end

1a- Enable visibility for variable 'DeltaTime'
2- broadcast "StartLoop"

Results:
When done in newly created project, it works as expected. But maybe because I have lots of methods running with the program, in the linked project it doesn't work as expected.

DeltaTime is shown on the play screen inbetween "0.020" and "0.040"
_deltaTimeClone is shown on the screen as 0.
When used in any operation, both act as 0, so DeltaTime is actually 0, but it is displayed as having value.
