You accidentally made a mistake in a citation in a submitted paper. For example, you cited a list from one author and you accidently made a mistake in one of the bullets. Let's say you added a word you shouldn't have or you missed a word. Is it ok to make those changes after the peer review stage? It feels bad to make such a mistake when citing a list, but hopefully it can be fixed later.
What do you think about it? In general, are these mistakes that uncommon and is it ok to fix them later?
How common is it that there are some mistakes even in published materials? Are they a reason for serious problems?
