Fixture At Fixture = Broken Update

I honestly hadn't noticed this before, but I checked in 1.7 and 1.5 and it seems also to do the same thing:

1 At 100

2 At 50

Store Cue 1

Go+

Fixture 2 at 100

Update

It works as expected.

However, this does not:

1 At 100

2 At 50

Store Cue 1

Go+

Fixture 2 at Fixture 1 /o

Update

Fixture 2 if left stranded in the programmer

This only stores fixture 3 and not fixture 2:

1 At 100

2 At 50

3 At 10

Store Cue 1

Go+

3 At 50

Fixture 2 at Fixture 1 /o

Update

Quote from FilipeQ

This is quite strange because I am using fixture x at fixture y quite often and it works fine.

you are updating with “original content” or “add new content”?

With Original content.

This example is with a new show and two fixtures patched and it fails every time.

1 At 100

2 At 50

Store Cue 1

Go+

Fixture 2 at Fixture 1 /o

Update

In this case Cue 1 is active with Fixture 1 and 2 Dimmer information. Fixture 2 @ 1 should copy dimmer information that already exists in Cue 1 so Original Content should work.

Fixture At Fixture itself does work but updating with information from the fixture copy does not. The workaround is to Store Merge but given that it works in MA 2, this definitely seems broken.
