Using a cable release, on a Manfrotto lightweight tripod, shooting with a Nikon D750 (or D5000) and a Tamron 24-70 lens so a different / sturdier tripod may be in order.
I've used the light weight Manfrotto BeFree tripod for a lot of night and long exposures and never had a tripod problem. I'd try a 2 second delay before the expense of a new tripod. Oh yeah, and make sure that the incline isn't docking while you're shooting if you're on that platform
