Prehistoric Kingdom Patch Notes — April 26, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
This PTB release is focused on quickly addressing the most commonly reported community issues - most notably input system bugs and unusable keybind controls. We hope this provides a more stable testing environment while we continue working on the remaining species for U17 and further develop animal combat.
How to Access the Public Testing Branch (Experimental!)
Right click Prehistoric Kingdom in your Steam Library
Go to Properties
Betas
Select 'ptb_public_testing'
Please note that it is not recommended to play Public Testing Branch parks on earlier versions of the game. Please send feedback and bug reports to our Discord server's appropriate channel.
Known Issues & Additional Notes
Stegosaurus is still being implemented so additional sounds and visual polish will arrive later
There is an occasional water loading issue which can cause old 'muddy' water to load with incorrect visuals. This can easily be fixed by forcing a water update, either through painting more water or replacing the water bodies with a different water type
Staff can be a bit unwieldy when using the breakrooms; please bear with us while we teach them how to take breaks!

Bug Fixes
Critical
Fixed several critical input system failures exposed by the initial PTB play-testing:
Patched a critical input error that would accidentally register certain keyboards as joystick devices, forcing the game’s input to not listen to the default mouse/keyboard behavior. Please let us know if this issue persists!
Fixed multiple input detection inaccuracies that would lead any custom binding’s application from failing with the ‘Invalid Keybinds’ error
Fixed an issue causing successful custom settings from being loaded across play sessions
Re-enabled camera mouse panning behavior
Fixed granular tuning of custom keybinds, with certain mouse-related keybinds now accepting any input types, whereas other keybinds strictly require non-mouse inputs
Fixed RMB (right mouse button) triggering GUI cancellation events
Fixed multiple keybinding layout issues in the Options Menu
Fixed an animal enclosure registering bug which would cause moving un-enclosed animals to deregister from important data
Animals
Fixed a mesh error causing immature Velociraptor to glitch out when far away
Fixed incorrect texture resolution settings for both Stegosaurus species
UI/UX
Fixed a silly last-minute oversight that could cause sandbox settings not to be synced up with the new game menu’s user settings upon loading a new game. It is possible that this also caused animals not filling their nutrition through browsing, even if players enabled this option
The ‘Not Contained’ and ‘In Quarantine’ headers in the animal management menu list now accurately update their animal counts and species widgets
Fixed the Tokod Locality excavation site not appearing on the excavations map
Fixed faulty logic for the ‘Animal Escaped’ park issue
Fixed an issue causing Loading Bay selection to not trigger when the Logistic Management View was open
Rendering
Fixed an issue where animal textures could be assigned an incorrect mip size during the nursery menu preview, causing the incorrect texture settings to persist for the rest of the session
Audio
Nursery animal preview individuals should not be heard outside of the nursery menu any longer
