Here is a strange bug I have encountered with Remote Tech on 0.90: I am experiencing a phantom roll when SAS is enabled. I've got a pretty heavily modded game (FAR being the chief gameplay mod) and at first I thought it was some strange FAR interaction, but it turns out that the phenomenon also occurs in space. And I emphasize this occurs only when SAS is enabled; turning SAS off stabilizes the craft. I went ahead and built a new craft just to guarantee there were no clipping forces and sure enough, same result. Stock crafts: same result. I went ahead and removed Remote Tech, and voila! No more phantom roll! If there's any debugging information I can get you, please don't hesitate to let me know. I'd love to resolve this; I haven't played with Remote Tech in quite some time and I was looking forward to a bit more of a challenge.
