Hi,

I experienced a freeze of the entire game, once i had a kill count of 3999 / 99.99% and it was supposed to go to hypermodule tier 2.
After a while (2-3 mins.) the game was back to working order - i presume some complex calculation/logic caused this, though that is just a guess ;)

Interesting, yeah when it updates the mod has to check everything (inventories, items on the ground etc.) to swap the old hypermodule for the new one.

This freeze will last a second or two on larger factories, which is bad, but I don't have a workaround yet. What you described sounds like a conflict that makes it take much longer than it should.
