Seems to me a part of the problem is that the fairings are not hollow anymore after loading the simulation, new colliders are automatically created to connect them internally. Maybe the properties of these colliders could be changed: only for shielding parts from the atmosphere while not creating problems with the colliders of the shielded parts.

Another problem is that it's no longer possible to decouple parts inside a fairing and have them move around. This limits the development of for example stock electrical engines and turboprops.

Azimech: Pointy fairings were never hollow. Interstage fairings are always hollow. So we will need a more complete report if you are really seeing a difference.

Beyond that, there is a fix to test for the fairing collisions in the next release.

Just want to confirm this is pretty consistent for me as well - I've had to stop using fairings in 1.3 altogether. I build a lot of ships with heavy payloads that are balanced on small decouplers or docking ports, and heavily autostrutted, but no traditional struts or fuel lines. My outer boosters are sometimes strutted to root, and my impression is that the weight of the outer boosters sags, pulling on the root part and crashing bits of it into the fairing. Oddly the same ship will sometimes explode completely, with the fairing decoupling from the lifter, and sometimes only a part or 2 will be torn off inside the fairing and smashed into the side. Same ship, no fairing no problems. Modded and stock both easy to recreate.

Edit - that Mohohoho.craft file is the one without the fairing, that loads fine. Now I add a fairing back to it and the problem is gone and I can't recreate it again. sorry.

This hasnt been a problem for a long time
