Help, Smoke effects only working for server host in Co-op

[Wanganui_Wildcat]

So I haven't come across this before but as the title says, the smoke effects are only able to be seen by the server host. Any idea's as to why that would be? The mission briefing is also only able to be seen by the server host, unsure if that is related at all.

 

Edit, to clarify the by smoke effects I mean the 'city fire' and 'village fire' effects.
