I get this error in log (and in error dialog at startup) when I activate both Transport Drones and Dupebox (by Dimava):
Error ModManager.cpp:1560: Error while running setup for recipe prototype "request-dupe-blueprint" (recipe): Recipe item-product "dupe-blueprint" is not stackable but has a max count of 65000.
Does this need some additional checks or is Dupebox doing something wrong?
