I play on the on the Thracian Frontier and have taken a big hit but when I checked my infimary no troops were in the free to heal section.  and I was hit just about an hour ago.  Any assistance in getting the troops that should of been healed back is most appreciated.

They attacked you in your city? It is the only way to revive for free.

If they attacked you in your city and they do not appear, restart the game, sometimes it works, if they still do not appear then it is a bug and we need more data: screenshot of the attack, etc. Look at the thread https://plarium.com/forum/en/sparta-war-of-empires/127_bug-reports/84528_creating-a-bug-report-2/  so you can see how to present a bug

Te atacaron en tu ciudad ? es la unica manera de revivir gratis.
Si te atacaron en tu ciudad y no aparecen reinicia el juego, a veces funciona, si siguen sin aparecer entonces es un bug y necesitamos mas datos : captura de pantalla del ataque, etc. Mirate el hilo https://plarium.com/forum/en/sparta-war-of-empires/127_bug-reports/84528_creating-a-bug-report-2/ , traducido al español https://plarium.com/forum/en/sparta-war-of-empires/390_tema-en-espanol/97041_como-informar-de-un-bug/ , para que veas la manera de presentar un bug
