Ah, now that makes a lot of sense, thanks for explaining! :)
I guess I was under the impression that tabularx required multiple
latex calls, instead of doing multiple trail runs during one latex run.
And I had no idea there was code to reset the global scope to some
Best solution for me will be to replace the tabularx use with a normal
