Basically the title explains everything.
I had a process builder calling an invocable method in apex. I updated the class to remove the invocableMethod annotation and the proccesss builder action has changed TOTALLY, and this logic has dissapeared.
In the flow-meta.xml metadata xml the main difference is:
BEFORE:
<actionName>cps_Helper</actionName>
<actionType>apex</actionType>
AFTER:
<actionName>01p0N00000CJADfNotFound</actionName>
<actionType xsi:nil="true"/>
So my question is, do you find this an expected behaviour? Have you ever experienced something similar?
