This week's פרשה contains many commands and thus, many instances of a וי"ו ההיפוך which changes the accent on the word. There seem to be a number of instances where the accent is not changed due to the נסוג אחור rule. Additionally, it seems the word ועשית, which appears numerous times, can never have the accent on the last syllable. If you know why, feel free to chime in.
In general, I do not correct misplaced accents for reasons I would like to discuss another time. However, I don't think it would be unreasonable to do so. Nevertheless, in those cases when the accent is not changed for circumstantial reasons, like ועשית, I find it very hard to justify a correction.
