SSTUAirstreamShield seem to have stopped working correctly. If you take SC-E for example, part in it will be shielded from drag and heat regardless if open or not, however part inside act like if they were not, engines will works etc and will have the flag "shielded:No" in action menu.

Can confirm that it is not working -properly-. it does appear to shield things, though does so even with the bay open. Part says unshielded, yet has zero drag. Cargo bay says 'shielded parts: 1', even when fully open, and still shields the test part even when open.

Unsure if this is caused by the recent changes to animation handling, or changes in KSP API.

Fixed; simple config error in SC-E parts that had unlinked the animations from the airstream shield module.
