Ask the Experts / Invisible Entrance Problem

So, I've been trying to make those invisibe entrances for the first time (using this guide: https://www.reddit.c...ranceexit_huts/ ), and pretty much everything went well.

However, I had to delete the track below the entrance for this to work, and after sucessfully completing the hack I wasn't able to place the track again. Though I can place it with Zero Clearance on it remains invisible. Any way to fix this? 

I am also looking for a way to make that entire boat ride (save the boats of course) invisible. Guides, hacks, whatever, throw it at me. 

You just have to re-do the hack if that's the case.  Sometimes it just bugs out and makes everything on the tile permanently invisible, so just re-do it an you should be able to build on it normally (with ZC of course).

I have the same problem days ago. But I solved it.

Remeber you should build the "dummy track" just below the entrance (that means you can't build it higher because the entrance is there), and the block just below the "dummy track". If you don't do exactly like this, for exmple, you build the dummy track two meters below the entracnce, you will get into the problem.

I hope you can understand what I mean.
