Trade

Traders can now offer any tech and talent in the game, not just a small curated set (147 talents and 134 techs, up from 11 and 10). Resource and mercenary offers keep their share of the offers.
Talents gained through trade now ignore your civ age's rune slot limit and building requirements. They still respect the Runeforge page capacity, exclusive talents, the King's weapon lock, and the [Runes of Fate] cap. A traded talent now shows in its socket even past your unlocked slots.
Tech gained through trade ignores building requirements, but still needs its prerequisite tech.
If an offer becomes unobtainable while your trader is away, the trader returns empty-handed and your gold is refunded, with a notification. The refund is subtracted from your gold spent on trade in Statistics.
Buying an offer that is no longer available now shows "This offer is no longer available."
Trading with a location you can't reach no longer charges gold. It now shows "This location cannot be reached."
The Trade panel no longer keeps showing an offer that has rotated out, and trade icons on the world map update as offers change.
[Kairn Anathul:] its second perk is now a free Geomancer, instead of 200 Prestige.
Fixed starting perk units from world map locations being blocked by the population cap before it had been calculated.
Reset Trap

Now reaches every tile within 2.25 tiles (the 5x5 area minus its four corners), up from only the 8 adjacent tiles. [Automated Linkage] uses the same reach.
Engineering Parts cost reduced from 8 to 6.
Minimum spacing between Reset Traps reduced from 2.5 to 2.
Fixed a Reset Trap that cancelled a running cooldown leaving the trap unable to fire again.
Traps

[Slicer Trap] and [Bomb Trap:] no longer need spacing from other traps of their kind. Slicers previously needed 2.5 tiles, Bombs 1.5.
[Spear Trap], [Poison Dart Trap], and [Bomb Trap:] fixed a trap that was reset and triggered again mid-volley firing past the end of its ammo.
Runeforge Talents (Traps)

[Adamantium Spear Tips:] Spear Traps and Floor Spear Traps now also deal 25% more damage, in addition to ignoring 25 armor.
[Adamantium Winding Springs:] Slicer Traps now also deal 25% more damage, in addition to the stronger knockback.
[Auto-Loader Mechanism:] now also gives Bomb Traps 3 additional projectiles, stacking with [Multi-Bomb Dispenser].
[Precision Mechanism:] now also applies to Floor Spear Traps.
[Repetition Mechanism:] Floor Spear Traps now fire 1 additional time, as well as the 2 for Spike Traps.
[Piercing Punishment:] a critical hit now applies an additional stack of Bleeding.
[Magnetic Resonator:] the pull now reaches a flat 10 from every Slicer Trap, instead of twice that Slicer's damage radius.
Runeforge Talents (King)

[Earthwarden's Runestone:] reworked. The first Geomancer's Sanctum you build now costs nothing except Prestige and can be built during any age. It no longer grants [Stoneskin]. Demolishing that Sanctum refunds nothing.
Geomancers

[Soften Rock:] now reduces rock hardness by 2, up from 1.
Difficulty

Custom difficulty games with a very low invasion strength no longer end up with no invasions at all. If no loadout fits, the weakest one of that size is used.
Custom difficulty caves too weak for any creature of their type now pick a type they can afford, and spawn their cheapest creature if none fit. Previously they could spawn empty and count as already cleared, handing out rewards for free.
Quality of Life

Hotkeys now keep working after you click a HUD button or a unit portrait. Only typing in a text field pauses them.
Melee units attacking a building now face the side they are standing on, not the side they were assigned.
User Interface

The Runeforge summary now shows the Culture talent slots.
Bug reports now include your Steam name and Steam ID so we can follow up with you.
Bug Fixes

Fixed units riding mining carts getting pinned at their stop and never dismounting when the rails passed close to it.
Fixed units falling off the map sometimes falling forever instead of dying.
Fixed the exit to main menu button not working after pressing Continue on the defeat screen.
Fixed an error when rebinding a key.
Fixed errors when quitting to the menu or restarting while timed summons were active.
