Patch 1.5.17
Unfortunately the upgrade to Unity 6 resulted in some old solutions no longer solving correctly. Although we tested old solutions as part of the engine upgrade, we didn't catch some cases that our users have reported. It's more important for us to keep previous solutions working

Poly Bridge 3 — Engine Upgrade & Fixes
We've just released an update for Poly Bridge 3. While most of it is under the hood, it's a big one: the game now runs on Unity 6, the latest version of the engine. This keeps PB3 on a modern, supported foundation and brings updated rendering internals along with it. You shouldn't notice anything different, just the same game on a healthier engine. This touches nearly every part of the game, so if anything looks off after the update, please let us know!
Improvements

When moving a node, highlight edges in red that constrain node movement
The gamepad cursor no longer shimmers along its edges while moving
Performance optimizations
Faster asset loading
Fixes

Mute and Mute In Background now take effect immediately when toggled with a keyboard or gamepad (previously they only applied when clicked with the mouse or after closing the menu)
Canceling the on-screen keyboard in Steam Big Picture / on Steam Deck no longer confirms the dialog with empty text
Fix visual pop that occured when exiting to Main Menu with gamepad
Cancel in-progress joint placement when opening Pause Menu with gamepad
Fix dev (help) solutions for RB-01 (Preplanned) and VT-13 (Near Miss)
Thank you for playing and supporting Poly Bridge 3!

We had some additional unexpected problems with the switch to automated looping Weekly Challenges. This update addresses all known issues... thank you for your patience!
Looped Weekly Challenges will now:
Use the same Gallery as the original Weekly Challenge
Have their own unique save folder (not overlapping with the original Weekly Challenge)
The Seasons dropdown menu in the Weekly Challenges UI now sorts seasons with most recent at the top (this is a bit more user friendly, especially as the number of seasons gets larger over time).
