Summary: Unable to add anything to build queues or change hero skills.

Description: Happened after turn 162; the game's sound suddenly distorted very heavily during combat, and my game has been completely wrecked since.

Repducibility: First time seeing it, pray it's the last as it just wasted five hours of play.

Expected Behavior: I expect to be able to play.

Version: 1.0.25 Steam preview.

Attachments: riftborn achievements.zip 

No local filesystem issues are afoot, and Steam "verifies" my installation successfully.

Oh, and in 1.0.25, this save also presents an "unquittable" game. Process hangs as soon as you try to exit.

Thanks for your report!

I tried your save with the 1.0.25 preview but no issue ... 

I made a new save if you want to try it: riftborn achievements.zip

If you still have problems, could you give me your hardware configuration?
