Stop recalculating routes!

Recently I took part in a gravel race, with a route provided by the organizer. I uploaded it to Karoo without any modifications, and I was surprised when, just a few kilometers after the start, Karoo took me on a different path! It's good that I knew the beginning of the route, so I could ignore the line drawn from the Karoo, but such situations are unacceptable! There were at least two similar situations at this race, and possibly more, about which I had no idea... And this isn't just a problem with this route, I've experienced this more before on my regular routes. Probably where the map did not is too accurate, or there is no road on the map, Karoo can change the gpx itself, created in an external service. This is really unacceptable, I understand that Karoo is aimed mainly at road cyclists, but there are still many other cyclists who also ride off-road, or on more complicated routes, or play squadrats or wanderer, where the accuracy of the previously uploaded route is crucial! Please solve this problem and do not change the loaded routes.

Evidence:

On the left route before starting - on the right same place after start a ride with following a route

An example from one of my previous routes. I create my routes very carefully in advance, I consciously chose the path to the right of the railway tracks, even though there is no official path there on the map. I uploaded the same route without modifications, but Karoo led me on the left side, suposly there is a path on the map, but it has been overgrown for a long time and is not passable and has not been updated on the map. Even though I'm riding with supposedly the best navigation on a bike, I had to check on my phone where my route was, because the Karoo itself changed my carefully prepared route...
