Connecting problem in rail tunnel

[Sique]

Playing with Simutrans 125.01 (Steam version Win64) and 64x64 r12334, I encountered a connection problem when trying to upgrade a tunnel from 120 km/h track to 300 km/h track.
The tunnel has a slope at this point, and the 300 km/h drawing tool does not recognize the present sloped 120 km/h tile, and continues with a level tile.
So I tried to upgrade it from the other direction, and successfully upgraded until the connection, but still, the 300 km/h drawing tool tries to continue on level.

I have screenshots, but albeit they are small, the system thinks the files are too large (PNG, 21.7 kB).

I think the problem is clear without screenshots. I will look into it. Which underground mode are you using, the cut though the world of full underground mode?

Next nightly (r12363) should fix this.
