Intensity issue for a Chaser w/faded Collection

[giacomo]

Hello,
while playing with Collection inside Chaser I've found a particular issue,
in the file attached there is a "Chaser time Step" where a Collection is played 2 times:
in the first occurrence there is no fade (0 sec) and everything seems fine,
in the second occurrence there is a fade time (2 sec) and the output of dimmer 2 is not correct,
it stays around 128 but it's easier to watch then to explain.
There is also a Collection copy called "Chaser time Default", with the fade timings from the scenes, where all the transitions are good.
