EDIT - partially solved: although nothing ever shows as "shielded" in the debug menu (under fairings OR in cargo bays), parts properly stowed in STOCK cargo bays are showing no drag once the craft gets going. Looks like an issue of bays added in mods (as far as drag actually being applied to stowed parts). I don't know how to delete a post, but someone who can may want to knock this one out.
I've searched and cannot find why my cargo bays won't shield anything from drag. I've knocked out all the usual suspects I can find, and here's what I've done:
1. I've used different types of cargo bays, both stock and OPT.
2. NO clipping anywhere.
3. Internal parts attached to nodes inside cargo bay.
4. Tried different parts
5. No external parts attached to cargo bays except inline by external nodes. For testing used fuel tanks of same type as cargo bay attached to either end with one random tester part inside bay attached to internal node, nothing else but landing legs attached to fuel tanks and maybe a drone core attached to a fuel tank to allow actuation of bay doors.
I load it up on the runway, look inside bay and parts (using debug menu) are showing NO for "shielded." Open and close bay doors, no difference. Used several types of different sized bays, mk3, mk2, OPT J, no difference.
*(edit) I finally removed all mods and made a simple tester as described above and had the same results, but I will list my mods here anyways, since I put it in the modded category.
CommunityResourcePack (didn't install this? came with another mod?)
Firespitter (didn't really want this one either...came with Infernal Robotics I think)

I am running 1.3 with all mods updated and (I thought) working. I'm trying to get some space planes flying around and I use cargo bays extensively, so this issue is killing me. Any help would be very much appreciated!
