For users who play Juno: New Origins on PC, there is a chance of a recurring issue on our air to air where the missile's failsafe fuse acts up without explanation, causing it to explode just before reaching the target. This affects all air weapons in our network, as well as any other weapon that contains the failsafe fuse code.
Your main two options are:
Remove the failsafe fuse from the missile guidance code.
Wait until it eventually goes away (this is what we did and it somehow began working again)
