Please upload the project.
It's a very big project (and my main project
).
I tried many many things:
1) renamed the routine (StartGame), using the "refactoring" and directly;
2) deleted lines apparently empty (and spaces, here and there);
3) recreate the project, using again b4j 5.51, both importing all modules and importing all module except that module, creating it again and "pasting" its texts;
4) same of above using b4j 5.00 and b4j 4.20
It was (and is) still there
