A fork of Factorissimo 2 focused on improving performance by implementing several 1.1 features. Can improve performance by 10X or higher. Also fixes several bugs from the original version.
When I pick up a factory, the interior is getting disconnected from the item/exterior. A while ago I got an error message when placing down a new factory building after picking it up, that was the first one to get disconnected. Now no factories are able to be picked up. They're still "lost" within the factory dimension - I can see them on the map - but there's no way to get them reconnected.
