-bug fixes
+several duplication tech give slightly lower duplication chance
+strange attractor now properly includes all your tech in duplication chance (it wasn't updated for recent duplication tech)
 
 ******************************************************** TODO ********************************************************
 
+give all duplicated power ups a half life that scales with the duplication chance
+  metastability reduces the half life
+  how to communicate the half-life?
