Edit: Issue resolved.
Would it be possible to add "mi_proxy.next_upgrade = nil" to the item prototype file?
Currently the mod fails to load alongside Bobs+Omni, I assume because something in those mods adds next_upgrade to the wooden chest which is subsequently copied into the module-inserter-proxy prototype. The game then complains that next_upgrade is not nil while at the same time the proxy-container mines to a hidden item.
Explicitly setting next_upgrade=nil on the proxy-container solves the problem.
