As the title says, enabling mods (specifically ones that add additional technologies to the game) and then loading into a save gives you more items from the "Early Bots" Technology.

Oh dear. That is moreso a bug with technologies that give items (which nothing in the base game or expansion uses). That said, although I have already made a system for giving out items when you research a technology, that only gives out 1 of each item (you wouldn't want multiple of a spatial cell with the same id). For something like Early Bots, I want to give it to all players in the lobby. Whether or not I should fix this is debatable because it's quite the edge case and the responsibility of the bug is not on me.
