Another hotfix out today, 7.2.2 working on addressing the CPU spikes and lag, and some other fixes:
- Blast furnace / Oil refinery should correctly no longer require a room
- Charred Fish now has the correct efficiency and speed skills associated with it
- Fixed washboard audio

Please let us know if you are continuing to encounter lag issues, especially if its happening at easily identifiable times.

Thanks!
