Updated revit and dynamo now many nodes doesnt work

i have 5 codes that were running smooth but after updates to Revit 2017.1 and Dynamo 1.2 some of the nodes dont act the same, either give nulls for specific items or empty lists or errors.
does that often happend after dynamo/revit updates? im still not using the 2 programs long enough and would like to understand how much can i count on the codes i do for the office as these codes are set for being standard actions we would like to perform on all of our projects.

I was able to fix most of the codes but im having trouble with these 2 nodes:

they just give empty lists suddenly…
