List<GameObject> trees = getGameObjects().all(t -> woodArea.contains(t) && t != null && t.getName().equals("Tree")); Without the area condition it works, if not I get ConcurrentModdificationException Can you explain me what I did wrong please?

Manly 878 Share Posted August 12, 2017 I get the same error again. Is woodarea modified by another thread? Link to comment Share on other sites More sharing options...
