When approaching a stiation with docked vessels, the RL10 engines with vacuum bells tend to re-activate themselves on those vessels. Not sure if this is a stock bug or if I should send logs?

Not sure if it is a stock problem, its been awhile since I've looked at the engine-deployment module and how it interacts with the stock engine module. Likely just an oversight in the deployment module code for an unforeseen start up sequence.

For this one, yes please, a log would be helpful. Preferably one from a short play-session, where the engine-activation is one of the last things in the session. Mostly I just need to know if there were any null-ref errors (or similar exceptions) around the time of the engine-equipped craft being loaded. In this case the log will likely be clean, and it is probably a mis-handling of how the module is initialized in that situation (reloading of a not-actively controlled craft; my only testing was on reloading an actively controlled vessel).
