I don´t know what upgrade caused the trouble, but at least for some weeks it have not been possible to use CTRL X and then CTRL V to insert the desired number of troop number you want to train.

What is causing the trouble is the field insist on having a number. If you clear it or try to copy your desired troop number into the field, it rewrite 1 or max troops all the time.

I don´t care about only being able to train a troop number ending on xxx1, but i find it highly annoying having to type the same number of troops over and over again. So please fix this one fast - thanks.

I would also suggest a auto trainer, where you just load resources and boosts. No one likes to train troops anyway. Also it would just equal the rest with those using a boot for the task.
