Description
This patch will update Star Ruler v1.2.1.0 to version 1.2.1.2.
Changes:
[Fixed] Crash with retrofit orders when using non-standard resources for construction (ie Ammo/Fuel in GA).
[Fixed] Reset camera on middle click was doing weird things with the camera in non-freeform mode.
[Fixed] Object.getMass() was not defined for const Objects.
[Fixed] 'SubSystem Unlocked' empire messages were not correctly linking to the stellar-pedia.
[Fixed] Stations built from other stations could sometimes not exchange resources with the original planet correctly.
[Fixed] Failed research sharing treaties could sometimes permanently remove research points from empires.
[Changed] Keybind for 'Reset Camera' now resets the camera to the angle it is in at the start of the game.
[Changed] Keybind for 'Reset Camera to Top-Down' now resets to an actual top-down view again instead of the default angle.
[Added] Bindable keys for zooming in and out.
