Carbon issue. Not able to patch this right now, but you can delete the line of code that is offending to get it to compile, only impact is that if you reset a water well vendor to default/vanilla, it won't re-enable rotating stock on that vendor.

a fix was posted on the carbon discord by snapple

Fix:
invisibleVendingMachine.nextOrderRefresh = Server.waterWellNpcSalesRefreshFrequency * 60f * 60f;
to
invisibleVendingMachine.nextOrderRefresh = ConVar.Server.waterWellNpcSalesRefreshFrequency * 60f * 60f;
