When we enter re-enforcement stage, we always find two countries pre-selected, the source and destination, and they are always the wrong countries, and this makes it very dangerous. A single wrong click can move all our troops to the wrong destination and suddenly end the turn, with no chance of acceptance/rejection and no chance of undo. This has happened to me quite a few times.
Please do not even try to guess what our move will be in re=enforcement, it will ALWAYS be wrong, because you do not know what our strategy is.
Re-enforcement should work only with a left-click and a right-click. First I can right=click any number of times to select a source country. Until I do this, no troops will move, because no country will be pre-selected as a source. After this, I left-click to the destination country to move the troops. A yes/no confirmation to check that I have indeed selected the correct countries before ending the turn would be welcome.
Upon entering re-enforcement, a hint "Please right-click the source country and left-click the destination country" will also be welcome.
Thanks.
