Been happening since Patch 1.6.1 nearly a month ago: [1.6.1] Can't see flames coming from Ironbreaker's Drakegun and Sienna's Flamestorm Staff
Most likely not a settings issue as I had the same settings before 1.6.1. I’ve also noticed that if the host is the one that is using the Drakegun, then I will be able to see their flames. If they are a client, then I won’t see their flames.
