Seeing as almost all troops spend several weeks or even months in the game files before going live, often with their spell descriptions finalised early on, one would assume even the weariest pair(s) of eyes would eventually spot and rectify these issues. Several weeks in the game files and several pairs of eyes equals hundreds of opportunities to implement fixes before pushing troops to live servers.
…Unless you’ve decided to look at new troops once and only once before okaying them…
You don’t need to stop the presses and send out new texts to your (totally human) translators to change ‘Annihiliation’ to ‘Annihilation’. Your favourite word processor’s spell checker would do just fine 
As for inconsistencies: This week’s troop ‘eliminate[s] attack by #number#’. Previously released troops ‘eliminate #number# attack’. This is not the end of the world by any means, but it’s pretty damn silly nonetheless.
A very brief search in your internal database, or in-game, or on a 3rd party website or just searching the game files would’ve revealed the phrasing that should’ve been used.
Again, ample opportunity for a lot of people between December 15th, when the troop was added, January 6th, when it was given its spell description, and March 1st, when it was released, to correct this.
Again, nothing that would require you to send out texts for re-translation.
