More performance improvement! :)

I've been grinding on performance improvements all day and I think the game is now about 20-30 fps improved over where it started this week.

Even running a debug build through Godot it's pretty smooth / at 60 most of the time unless I max the sim area.

And I think there are probably additional improvements I can still make - this bodes pretty well for possible future additions to the simulation...

Other misc:

• BUGFIX: fixed MENU_SETTINGS_LABEL_CONTROLS_ROTATE string that was missing from localization

• BUGFIX: fixed IsBuilt flag (crowbar destructibility) on some variants of placed Heating Element

More coming soon!
