It’s not necessary. When you type “-1” it’s calculated again. Now I have a bit more than 5K. It should be fine, but it looks like that for some obscure reason, the minimap was damaged and won’t regenerate. Is there a way to “flush” it’s cache, fore it to regenerate ? Right now, I can barely click on the weird partially drawn parts but the level selected is absurd and the map has become useless, making my life miserable to place anything in the world
