1.12d Update / February Build Challenge

10 Feb 2026Developer post

This months update contains the following changes:

Version 1.12d:

added one new wall lamp for generic theme
updated individually placeable windows to be resizable
removed collision from flower boxes/flower patches
disallowed deleting guest spawn tiles if "Allow building outside park bounds" cheat is enabled since it can make the park unplayable
fixed guests leaving the park when they didn't want to if "Allow building outside park bounds" cheat is enabled
fixed a multiplayer desync that could happen if some players (but not all) own the Dinos & Dynasties DLC and researching decorations
fixed windows of spooky theme walls not being recolorable
