I thought I understood how and where TM2 stores its bundles, but clearly not. I now discover that a bunch of bundles have spontaneously moved from /Application\ Support/TextMate/Managed/Bundles to /Application\ Support/Avian/Bundles, and some of them have even duplicated themselves: […]
The “Managed” folder are for bundles in their pristine condition.
If you edit a managed bundle, a delta is created in ~/Library/Application Support/Avian/Bundles.
I would expect your “duplicates” to be delta bundles (with your customizations).
Presently even when reverting an edit, the (empty) delta bundle is not deleted. This might leave a bit of harmless clutter in the local Bundles folder.
