First of all: The bug.
I'm pretty sure you all already know how this works, but in the rare case you haven't faced this bug yet, I'll teel you what's the deal with the Shiel/Field in 3 words. IT. DOESN'T. WORK. As simple as that, you cast it and it's like it has no effect in the game whatsoever. This doesn't happen eveytime, but to me happened at least 3/5 times I used these cards.
Second of all: The disappointment.
Years ago, I used to play this game. Recently, I've started playing it again, and I realized that the "Dissipation Shield/Field" bug hasn't been fixed yet. I can't believe is that hard to resolve it. Makes me think that the developers abandoned this game years ago, or that they just don't care about it at all. Both of them are sad
Whatever, I'm just reporting this (again) in hope of you'll allow me to use the Dissipation strategy...
