Hi @ll2pakll ,
Please excuse the delay, your topic somehow slipped from my list.
I can only speculate here, as you haven't attached a sample scene that highlights your issue.
The way you describe the problem it looks like a priority issue of the python tag. Please have a look at how the priority works in our documentation: https://help.maxon.net/c4d/2023/en-us/Default.htm#html/TPYTHON-OBASELIST.html#EXPRESSION_PRIORITY
Also note that it's forbidden to call c4d.EventAdd() (or in reality is just skipped) from the python tag due to multithreading restrictions (c4d.EventAdd() is executed on main thread whilst python tag is executed in a parallel thread):
