Empire "Send Reinforcements" Event: Reinforcements Arrival Direction Broken

[beppu]

I started my first campaign as Reikland today. As you know and I found out, there is an event when an Empire faction is attacked by savages like Greenskins/Norsca, that allows the Emperor to send reinforcements.

Twice I have decided to send reinforcements to aid in the battle. However, those reinforcements deploy in the fight BEHIND the enemy deployment zone!
The first time this happened, the Greenskins luckily had no cavalry and I was able to very narrowly make a dash for it along the borders of the map, as the reinforcement army provided by the event is only a few units strong. Now against Norsca, however, there are plenty of enemy units that are going to outrun mine and will just crush my army together with the rest of their troops before AI Talabecland arrives.
The wrong direction would hardly bother me, because the spawn point is in a forest still. However, the AI somehow seems to know my exact position despite all my troops being invisible, and immediately focuses me down.
I find this quite gamebreaking, as it means that the reinforcement feature is basically just a waste of money (I assume "send mercenaries" has the same issue, making it a waste of prestige), in other words I pay only to not have the fealty of an elector count decrease and then watch a few hundred good men die for no reason whatsoever.
This needs to be fixed ASAP, as it destroys both immersion as well as my will to touch Total War titles. I have read in countless forums that this is not a new issue in most battles, where reinforcements will spawn on wrong sides, but in this case it just strikes me as especially stupid, frustrating and unnecessary.

It is also quite audacious that CA have not found and fixed this bug by themselves... How much do these games with DLC cost again? I better not remember...

In addition, I noticed that I have to pay upkeep cost for the reinforcement troops the turn after the event, despite them getting disbanded immediately after the battle and me having already paid them through the event.

It is not a bug. It works as intended. I agree that it is bad.

The upkeep cost, I was unaware of.

There is no wrong direction in a quest battle, if you can teleport to battle, then it means that even if you go to battle walking the place where your army will appear is predefined. I haven't played with Empire after the upgrade yet, but I suppose this event works like a quest battle.
