Reported on discord: rasiermesser weapons like the Valjor 200 and Ion9 are not correctly gaining the +Omni enhancement from the device slot in 1.9b1. Probably related to: https://ministry.kronosaur.com/record.hexm?id=91298

Starting Valjor 50 has omni.
Replace 50 with 200: no omni on 200.
Replace 200 with 50: omni on 50 again.
Install 200 as second weapon: both 50 and 200 have omni.
Remove 50: 200 still has omni.
