As long as you've selected the correct folder, the error message isn't as important. Thought if you're using the Steam client, things can be broken.
When you install a crosshair, you need to select the proper crosshair in the ingame settings menu.
Please attach log files.
But I'm guessing it's an XVM issue, I'm getting the same, and I know multiple others having the same issues.
Not easily tested though - as it requires playing those special battles - replays work fine, so they won't work for testing.

And besides that, there's an ingame menu - I believe it's when you click the cog in the top left, before you actually exit the game, it should be there.
Here's a tip since you said you don't care about 'optics', I'm guessing the looks of the tank? And you just want the bonus:
Are you aware that you get the camo bonus if the camo is only mounted to the hull of the tank?
Meaning the '6 of type 1' could fit 6 tanks.. if you manage to have 6 tanks in battle, you might wanna reconsider yolo-rushing
Best bug report ever.
"Freezing my game" - and no info beyond that.
No logs. No help.
Thousands upon thouands of others are having no issues at all.
Could even be your computer, if we're just going to throw guesses at a game freezing.
Wargaming had the intelligent idea of adding the minimap stuff into the same graphics file that contour icons are in - meaning it's a LOT of extra work to make things work and what not...
But if you ask nicely - and tell Aslain which contour icons option you're using - he might make it custom for you. (But it'll partially break whenever they add new tanks I guess)
You don't have to clear every time you install (unless you don't have that much DLC that needs downloading, then you could just clear it every time)
Otherwise if you have large DLC selected, you could keep an eye on changelog, and if you see something related to your selections, you could clean when they are updated
Just in case
Because other regions (usually ASIA) is always behind in patching the game..
Holy hell, 1742 MB DL cache.. you should clear that every now and then, if you have old files there they don't get fixed properly sometimes
Aha - yeah you are... I didn't catch that part
Looking at tanks.gg, it looks like the mark is aligned for the stock gun actually.. the barrel is positioned lower, which would probably align with what you are seeing in your screenshot.
The mod probably doesn't take into account the different guns, if you're using stock gun for example?
Probably something for the mod author to know about
