Description

I'm using blueshift's warp drive to enter a distant system. As soon as I entered the star's SOI, the framerate slowed to a crawl. Inspecting the log shows that this exception is getting spewed:

Since the warp drive translates the ship without changing its velocity, I'm sure my ballistic trajectory's transitions are a little bonkers. But I'm pretty sure you could cause this to happen without mods too.
