Something's up with component.transform (edit: all good)

Hello, I had written a very simply filter to run on export which decomposes transformed compmonents (for TT exports).

The code is as simple as this:

for component in layer.components:
	if component.transform[:4] != (1, 0, 0, 1):

To my horror, I found that the filter decomposes a lot more glyphs than it should. It decomposes basically everything.
However, when I run the code from the macro window, it doesn’t.

For example, adieresis (no transformed components) gets decomposed when I run the filter (wrong behaviour), but it doesn’t get decomposed when I run the code from the macro window (correct behaviour).

What is going on? How can I fix this? Thanks!

EDIT: My sincerest apologies. I hadn’t loaded the latest version of my filter, as it wasn’t in the plugin folder as an alias. Everything works fine and as expected.
