Alright so it´s currently not possible to repair the hero ship. Is this actually intended, is it a missing feature or what´s happening here?

Some clarification would be good, because I think it should be possible.

I think a dev mentioned that you currently have to select 2 fleets to be able to see and select the hero's ship for repair, and that it's going to be improved soon (along with a 2/3 reduction in repair costs). On the bright side, I learned that hero ships come back to life at 1 hp as long as you win the battle because of this issue

Might potentially save a lot of dust putting off those repairs if the hero ship has mostly long range weapons and gets utilized well enough before it dies.

If you enter the upgrade hero ship screen , you can repair it there clicking apply without upgrading i think (always repaired it with upgrades)
