As Title Says tried to input speed module to assembler mk2 and the game freeze's no crash or error just not responding
game version:0.17.68

Can you provide a save game?

just had the same bug, but with a beacon. had to kill the game with task manager. here is the most recent autosave ~2-3 mins before, and the factorio-current log file, in case that helps. https://drive.google.com/open?id=153I1ZXoswtwxrG6L7iGhRUnZPmVoc8sy

edit: the bug happened when the bots attempted to build a beacon with 2 speed 3s that i had just ghosted next to me using copy/paste. at the time i did not have any speed 3s on me, and had just finished handcrafting the beacon. this was all also inside my main robot network, which had speed 3s but no beacons.

Hi, had the same issue as well. If I remove the drones from my inventory and get some modules it works without issue. When they are in my inventory, as soon as or a second or two after the bots install the module, the game freezes.
