in the last weeks I sometimes get an error editing an parameter.
The bug is annoying because if I want to change the parameter i have to close the project and open it again. Then I can change the parameter.
Part of the error message is in german. The translation is something like, when that helps:
An error has occured:
The reference of the object has not been set to an object instance.
Please contact support.
My current version is 4.7.2.
