As of 1.19 The Memory Leak Is OUT OF CONTROL
FIX THIS
The game is almost completely unplayable in this state (a whole six minutes between the crash, last time).
Please swear up and down you will not release 1.2 without nailing down, and murdering the memory leaks.
I've e-mailed stardock support and codecritter a pile of error files with saves, to help your ruthless murder (so far unsuccessful) of this bug.
