Patching and maintenance is currently underway.

I currently have no estimate for when this will be done, but expect several hours as database cleanup and automated error testing is performed.

You can follow the progress here: http://www.godsandidols.com/topic/1133/

This is a fairly major patch that overhauls all buildings and resources.
Their costs, production lines, new mechanics (Electricity), and so on.
You can expect patching to take a little bit longer than usual because of the extra tests I'll be performing to make sure everything is working as intended.

I tried, down to the literal last minute, to figure out a way to not do a wipe, but it is unfortunately unavoidable as the changes to buildings and resources are too great. So in no uncertain terms: There will be a full wipe.

If you have any questions I'll be on Discord https://discord.gg/VBCcZFw and I'll keep an eye on the Steam discussion forum http://steamcommunity.com/app/423890/discussions/ as well.
