I might be getting hit with weird multiple bugs because I've been shoving everything in the same town portal. I noticed bread wasn't getting teleported off at all for a while, and maybe still true, and I'm at tier 2. It might be related to letting the previous tier count for the current tier's sustenance/population decrease stats.
I'm getting this bug now when I do /homeworld stockpile (it worked previously):
1661.175 Error MainLoop.cpp:1195: Exception at tick 2794028: Error while running command "homeworld": homeworld-reloaded/scripts/homeworld.lua:94: attempt to concatenate local 'item' (a boolean value)
