Unrailed 2’s latest experimental build tackles China connection trouble and a bot crash
Build v-916-6b85f4a adds a new "Photon China Transport (Experimental)" setting in online options and fixes a regression that crashed the game when using the bot.

Indoor Astronaut pushed out another experimental update for Unrailed 2: Back on Track on Steam, and v-916-6b85f4a is focused on networking and stability.
The biggest addition is “Photon China Transport (Experimental)”, a new online settings option that uses a different network and relay architecture. Indoor Astronaut said it should solve issues in China, and the team said it had already seen positive feedback about the change in Discord.
This build also fixes a regression crash tied to using the bot. It follows another June experimental update that also worked on crashes and bot behavior.
