New update problems

Hello everyone,

after today update, i got a strange problem on my server.I did everything i do every time a new update comes out, i saved world data, installed new update on server, because its modded, i installed oxide and oxideIO and start server again.
All players are dead by auto turret, there are no buildings (player made) on map, and they lost all the loot.
I was sure that saves are corrupted (that never happens to me before) so i deleted few of them and forced older ones but i cant bring back player bases and loot.
Any advise on this?

Maybe forced map wipe today?

Remember to read the devblog every time there is an update, it clearly states on the very first line even, that there is a mapwipe.

Typically map wipes occur on the first update of the month, like this update

I am having problems post-patch. Whenever I log in, I get the following error repeated a thousand times at startup. I also cannot log in to any server.

"This custom render path shader needs to have at least 2 passes. "

I have never had this issue before.
