Please standardise on either losing or rolling over the armies in both cases.
If a player skips a turn, they get the armies next go. However, if they click 'begin turn' then perform no other actions, after the timeout the armies are lost. I missed out on 7 armies in game 278997 like this.
I think the armies hsould be lost in both cases, but a sudden change in game behaviour like this would disappoint many users, so perhaps rolling over in both cases is the best option; a decision should be made if we will also allow players partial deployment, holding a reserve of armies for later turns.
Perhaps it should be a deployment option, like fortification is.
The current behaviour is inconsistent, and it means that someone who _tries_ to have a go is worse off than another player who doesn't even bother.
Priority 3 I reckon.
