I'm playing Space Exploration with this mod and the SE Space Trains. Whenever they go through the Space Elevator, the message "MUTC Balancer Ignoring Invalid Inventories" displays, which is a bit annoying. I've disabled the MU Control Debug Messages, but the messages still keep appearing.

It would be nice to either fix this bug or let us disable those messages...

I'm guessing it might have something to do with the spent fuel that is in the output of the trains...

Thanks for the report. That message comes up any time a loco is destroyed (including by the space elevator). It should be included in the debug msg toggle, will fix it soon.

This should be fixed in 0.4.18.

Awesome, thanks!
