Automatic combinations ignores wind when seismic is combined with temp

Hi,

 

Any body have any ideas for this problem with automatic combinations?

 

Firstly, all combinations appear to be working correctly, but then...

 

When I combine Seismic with a Quasi-Permanent Temperature (both in Seismic load type), when i run the automatic combinations wind is completely ignored.

 

If I delete the QP temperatures, all is ok.. So that means I cannot combine Seismic Loading with Temperature?

 

e.g.

I want [Seismic] AND [QP Temp] so have them both as Seismic Cases, but when using the relations, it removes the wind loads from the ULS combinations.

 

In the model attached, when you look at the Automatic Combinations, no wind is accounted for, but if you delete the seismic relations, it appears!  Seems strange...

 

Any help greatly appreciated!

 

Thanks
