I took a look at Astro Trains this morning, and found out that their guns had simply been... disabled. Not sure what the story was with that, but I've turned them back on.
In terms of the etherjet behavior, no -- that's something that I guess Keith is planning, but it's up to him.
Will have the new version update out in a few; I also snuck one other last thing in there, a good idea Elok had.
