I seem to be having a unique problem exclusive to the OPT-J Deployment Bay. Any time I include the OPT-J Deployment Bay on one of my ships, the ship "launchs" at ~1,100 meters in the air and proceeds to fall immediately to its death. I tried troubleshooting down to the point where I removed all of my other mods (I use about 15, mostly graphical), tested them against each other for conflicts, and then uninstalled/reinstalled a clean KSP, and then added OPT. It's the strangest bug I've ever encountered. Is this happening to anyone else? A known bug? Any fixes? I was looking forward to using that part for VTOL projects.
