I'm trying to change a rocket to have folding fins with Overload, as it shows that the parameter exists. I've tried changing it from "Static" to "Fold" or "Folding" but it doesn´t work. It does absolutely nothing. Also, for some reason, Windows somehow thought my language was set to Spanish. It showed every word in this post between "Static" and "nothing" as a spelling mistake.
A few minutes after I posted this, I realised what I had to do in Part Properties. Also, I redownloaded the English language on Windows.
