Yes, that is only in the log, so that it is known what happens.
It does not affect or crash the application itself however, the exception is correctly handled.
I might remove logging from scripts in the future, but decided to leave it there for the alpha versions.

[biggbest]

Ah right ok it's just a log, though it was a real internal error (missing null aware or something) :-)

[Hax Simulator]

Actually, the exception is caught, logged, and handled, so the code is aware of it. The code just shouts it out to the log, and after that handles it regularly. :)
