Space Exploration - reactor interfaces not being autocreated on Antimatter reactors in K2SE automatically and the hotkey does nothing. However they seem to appear "later". Potentially on reactors on ships once they have taken off at least once. As in the creation/deltion/copying that SE does when a spaceship takes off/lands results in the interface being created???? but no interface on hand placed or BP placed reactors.

Regular vanilla reactors work fine though.

On Antimatter reactors there is no combinator looking sprite, just the light, and the light is faint.
