Hey, sorry - v 1.9.3 had a pretty major bug that made the game not work like at all. It's been fixed now and v 1.9.4 has been uploaded.
Sorry for the issues this might have caused.
One bug i noticed is that if you're deploying an army and hold shift while dragging a unit card, you could continue to just multiply your selected forces. This was 1.9.3 though. I'll text 1.9.4 and get back to you asap
