All the stability derivatives are in the green. I've also ensured the center of lift is to the rear of the center of mass. To be clearer, these images were taken on separate launches, and on these separate launches, the craft performance is very different. There is no rudder, but it flies fine without it on some launches, and flies terrible anyway when i do add a rudder on other launches

Hi all! I need some help with some aero force asymmetry. I have a perfectly symmetrical plane with one intake, and one thruster, so asymmetric thrust is probably not the issue. This issue is also intermittent. I've uploaded the craft file, and some images. KSP version 1.3.0 FAR verision 0.15.9 Liebe Other mods AFBW, VesselView, JSI, KIS, KAS Craft file: https://drive.google.com/open?id=12ky25EgSyq17K4aUO7eKi3H64fidhuoC This issue also occurs for the FAR craft, and it happens intermittently on launch reverts. This is the craft functioning properly. https://drive.google.com/open?id=1r4SUu1KT7CNOnFPv5378zy9-kQVJ4a_K Here the asymmetric forces appear. https://drive.google.com/open?id=1iWmvX9N4dVmahuMx-ZWampzJimBO-C9t note that at the moment those two images are taken, I am not providing any input for control. note also the yaw drift, the roll compensation in the staging panel, and the aero force on the craft.
