Really? I didn’t notice anything like that... Perhaps because english is my third language (or fourth, not sure already)
There's quite a bit, but like I said, for the most part it's harmless, gets the point across, just comes across as a bit awkward. There was one instance where I'm not sure what it meant, but that's about it. It's a lot of apostraphe'd words where using the two separate words would sound more natural, or the tense being the wrong one. Not really things being spelled wrong, just not quite the right words in the right places.
