it's been a few months I'm using Simple Planes but since last 2 days I've been struggling with the issue . The missiles won't lock on the target , and rest of my built and downloaded mod works fine. I did build few planes and the missiles on it works totally fine . I do like modifying the missile characteristics in xml and there's a bunch of my own functional mods. Can anyone help me out , am I missing something ? I thought about reinstalling but I don't wanna loose my mods .
Backup your mods and reinstall.
