v1.3.4 fixes a bug introduced with instant combat in v1.3.1.
Flee No Longer Damages Your Ship
When you encountered a non-aggressive NPC and chose to flee, your ship was still taking damage and could be disabled — even though you never attacked. This happened because combat was being resolved and written to the database the moment you entered the sector, before you made a choice.
Now combat is computed instantly as before, but the result is only committed when you actually hit Attack. If you flee, nothing is written and your ship is untouched. Ambush encounters (where flee is not an option) are unchanged and still resolve immediately.
