Mfix rolls back to version 18.1.5 under conda 4.6.12

Conda has an update from 4.6.11 to 4.6.12 several days ago, but when I update my conda to 4.6.12, my mfix rolls back to version 18.1.5 even if I re-install it.

Though I can solve this problem by downgrading my conda with command:

conda install conda=4.6.11

I believe this problem may need to be solved by official developers to avoid confusion .

I have MFIX 19.1 installed with the latest conda (4.6.14); I do not see the MFIX downgrading issue.

Could you post the output of the command conda env export -n mfix-19.1 ? (Or whatever you named your environment, if not the default mfix-19.1.

I just tried again and it seems that this issue no longer exists. May be there was some thing wrong with my environment several days ago.
Thank you anyway!
