Does anyone remember Undersea tunnel before 99.17?
This is a bug before 99.17. Many Hong Kong Simutrans players use this "function" to build Undersea tunnel.
Can open the bug or just add a function in Simutrans?
That bug had been removed before.
Use latest nightly version, you can build real undersea tunnel with underground slope tool.
May it work in 103?
No. You can't dig a hole on sea anymore.
But you can dig a real tunnel under the sea with the underground slope tool. (just reiterating :) )

(In 99.15)
And as it has been said, that will not work again any more.
Use the new "UNDERGROUND SLOPES", and you can build a tunnel under the sea.
Are you understanding what we're saying? That will not work any more. But there is a way you can do it. With Underground Slopes.
