When an object is phased multiple times, damage from being forced into phase by reality stabilization now occurs only when the last effect is terminated.
Changed the message when you try to remove an unremovable cybernetic implant.
Items that affect the chance of salvaging multiple bits, like advanced toolkits, are no longer used on items that can only ever disassemble into one bit.
The random-buy mutation choices should now be more stable for a given seed.
If you're out of 2+ point mutations to buy, you're now presented with 1-point mutations.
The look and target picker "Locked" status toggle is now remembered across games and reloads.
In the classic UI, the cooking menu now reutrns to the selected option instead of the top of the list when you choose a recipe to cook then decide go Back.
Dromad trader psychic thralls or domesticated slaves no longer generate map notes.
Geomagnetic discs can no longer spawn with elemental damage mods.
Made some improvements to geomagnetic disc pathing.
Fixed an improper item ownership warning when you tried to examine or disassemble items in the inventories of certain creatures you were dominating.
Fixed a bug that caused Flurry to not work on inanimate objects, which in turn caused NPCs with flurry to stand there inert instead of attacking inanimate objects they were angry at.
Fixed some bugs with color rendering and formatting in books.
Fixed a bug with liquid-fueled power consumption, such as in gyrocopter backpacks.
Fixed some performance issues with normality gas and norm cores.

[debug] The "Do you really want to die?" promp no longer accepts space or enter as input.
[modding] The map editor now supports Ctrl-C to copy a selected region, which turns your brush into a rectangle the size of that region. Ctrl-click pastes the copied region, and right-click deletes the region bounded by the selected rectangle.
[modding] The map editor now properly renders most walls, water tiles, and fences.
[modding] The map editor now has tile previews in the blueprint selector.
All of the builds are delivered same-day to GOG; if there's an issue it's somewhere on GOG's delivery side, which I don't have any control over. The latest build in my gog control panel is the same as steam.
