Unrailed 2: Back on Track Brings Lab Tunnels and Fixes to the Main Branch
Version v-1046-2790039 bumps crossplay to 151, with console patches scheduled to go live alongside the update.

Unrailed 2: Back on Track’s main branch has been updated to version v-1046-2790039, bringing lab tunnels, map-generation fixes and other changes into the main build. The crossplay version now stands at 151. Console patches were scheduled to go live alongside the update, with Indoor Astronaut saying they would bring new features to console players and address inconsistencies from the previous patch.
Several changes had already appeared in an October experimental build, including loco-labyrinth tunnels, faster map generation, controller-disconnect fixes and corrections for rare missing lab boxes or bolts. The main-branch update carries that work forward alongside additional map-generation and bot fixes.
The latest map fixes address a Canyon generation hang caused by stale sandworm sources and cases where map generation could take a long time or fail to finish. Generation should also be slightly faster in boiler badlands. Bot changes cover bucket and track tasks during wagon loading and lava bridging, as well as carrying brake tracks to the front of the train.
