Fixed the barrel problem in the upcoming update.
Fixed the stack overflow error (Can't believe I didn't find this one myself in testing).
Fixed saving in upcoming update as I implemented a new saving algorithm that saves literally everything in the game. I originally didn't save conveyors and building in the prototyping version as it was extremely slow if there was a lot of conveyors.
The router is trying to output to the barrel but can't because it is full, then swaps to another tower to output to but that has a delay. I will remove the delay in the next version.
Thanks for all the help as I really appreciate it!
