Cisco ASA 9.4: Configuring NAT

I am upgrading from a Cisco ASA using IOS 8.4 to a new ASA using IOS 9.4, and while I was able to copy 99% of the configuration over to the new 9.4, I cannot get NAT to work for static NATs. Traffic is not going through the outside interface from these inside systems. The NAT (dynamic) for all inside hosts works fine, but the static NATs do not.

Specifically, the hosts 192.168.112.3, .4, and .5 cannot reach the gateway (PING or other). However, inside hosts on 192.168.91.xxx have no program reaching the gateway.

Could someone please look at this configuration (see below) and see if you can spot why static-NAT hosts on 192.168.112.0/24 could not reach the gateway or get 'outside' at all?
