Rule in interpreter causes an NPE in unrelated piece of code
In a project I have noticed that commenting/uncommenting this rule causes an exception:
This seems true for all the rules in these languages which have constraints (i.e., they specify the type of the values they work on).
When they are active I can build the languages in MPS but the build fails from the command line

This has been puzzling me for a whilw and I am not sure how to investigate this further
- https://youtrack.jetbrains.com/issue/MPS-30286 is a bug I reported about NPE being thrown from BasConcept.getPresentation() if the concept isn't loaded.
- I think I fixed this part of the code in mbeddr.core in commit f12ef509ade78c50ab2fdf483e676dcc571fc83a in both master and 2019.1 version.
Unfortunately I am using the 2019.2 version. I have updated the dependencies this morning and I am still experiencing the bug
Thank you for the pointer! For now I have created my own sub-concept of TypeChildConstraint where I override getPresentation. In my case it should work as a workaround
I am closing because this was fixed a long time ago in mbeddr and MPS.
