Good luck to you guys today, and we will see you there!
It was nice to meet you yesterday!

I've got a few reasons why I think moisture intrusion might have been the case:

First, it wasn't as if a few components just rusted, there was a concerning amount of condensed water inside the bag that did not evaporate when the bagged robot was warmed up again. This implies that extra moisture was inside the bag.

Second, we have bagged in warm environments numerous times, passed through a cooling cycle, and never saw any moisture condense inside the robot bags before, let alone seen rusted components.

Third, and most importantly, the bag had several small holes it in from being transported in the back of a truck. The robot was loaded into a truck while it was raining outside, and then driven for four hours (mostly covered in a tarp) while it was raining/snowing outside. This provided ample opportunity for moisture to get into the bag. It is possible, if not likely, that the cooling of the robot/bag drew moisture and cold air into the bag though.

Fortunately we now have a trailer to transport everything with, so hopefully this occurrence will be a one-time fluke.
