Seems like this user got a solution - but...I can't see what that was? How to fix?I've done tests of just closing and reopening the program, but it didn't happen. However, it is not every time that the problem occurs. As you can see, I already marked the case as solved, however it happened again. I've fixed the files again, worked, closed everything, restarted the computer 2 to 4 times and so far everything works fine.
Thanks!
