I’ll add to the list as I remember/encounter them, but these two cause me some major R&R (Rage and RSI) today:
- StringTables can’t be updated by right-clicking and selecting re-import, like almost every other asset can (including DataTables). You need to open the asset, and click the “import CSV” button. If there’s any formatting error in the CSV, you will not get any error message (or even anything logged what I can see).
- You can’t implement an interface function as a function… unless it has an output return value. You need to add a value you don’t want, implement the function, and then go back and remove it. Otherwise it always becomes an event (yes, I already reported and had this confirmed, but I still don’t see the fix in 4.27).
