What kind of mistakes do you make? I'm finding that ei/ij is something I now need to look up regularly. Vocabulary sometimes takes me a second to remember (new words, that I learned after moving away, probably as much as old words), or whether an expression/saying is Dutch or German or English or an Internet reference, but nothing is a hindrance to fluency as much as the dumb ei/ij thing—that we could simply have abolished centuries ago instead of learning it by heart for generations—since I need to really pause and do an external lookup instead of thinking/umming for 500ms For others who read this: ei/in is like whether to write cocoa with a c or a k, if both letters were equally common (it's a 50/50 split with no logic to it) and sometimes the other variant has a completely different meaning
