Very large differences in temperature loading on a few members when upgrading from 2019 to 20222

Hi,

 

I have a model that I am trying to upgrade from the 2019 version to the 2022 version. I understand that the temperature model has changed between these two versions however I am getting absurdly large differences in forces (in excess of 100kN) for a handful of members and the rest of the structure is very consistent between the two versions. All other load cases give values very close across the version. The main members that are different are 47 744 1150 1178. As can be seen in the spreadsheet screenshot I have attached, some members have up to 1000kN difference between the versions. 2022 also shows massive differences in force at either end of the bars in some cases, whereas 2019 is much more consistent.

 

Thank you for any help you can provide
