Same, I stopped playing because of this (and the lack of an answer of whether this would change or not), and another issue I am having where I cannot recruit any vassals, despite 100 relation, and literally billions of gold (cheated in to test). Didn't even feel like reporting the second issue, because of the lack of resolution, or even confirmation that this is a bug or design choice.
Yeah, I agree with this. A lot of times I would set my cavalry to mop up, then just order my infantry into some sort of "victory" formation, just killing time until the cavalry was finished. It was fun at first, but did get kinda tedious. Now, I have to do the annoying guesswork to make sure cavalry can mop up, and then either have to run around trying to help mop up, or literally just sit there and wait. Doing something to make the end of battle more fun or shorter or whatever is fine, but just disabling controls is not the way to do it.
Awesome, thank you! Just want a concrete answer, so I know how this is going to proceed.
UNLESS you already had units set to charge or advance. According to @MArdA TaleWorlds, once the enemy routs, half your units should stop and start celebrating. This isn't what we are seeing. Right now (in 1.5.10), any units currently advancing or charging continue to fight fully until the enemy is completely depleted. Any units holding, shield wall, etc., will cheer 100%. And during routing, you can change NONE of this. This is why it appears to be a bug- the player completely loses control of the battlefield when the enemy routs, cheering/not cheering is irrelevant.
