Can't edit Silverfish, lots of unrelated compile errors

[Gorm]

The bot doesn't seem to value vicious fledgling more than a regular 3/3 creature.

So I tried adding this to the getPlayfieldValue in BehaviorControl.cs

                if(m.handcard.card.name == CardDB.cardName.viciousfledgling)
                    retval += 1;

Unfortunately when I restart the bot, it spews out a bunch of unrelated compile errors. What's going on? Is Silverfish not being maintained anymore?

Hmm never mind I had a typo in the code. Is it possible to compile silverfish as an external exe still so I can use visual studio? Or is it not safe anymore?
