Part of Grand Porto map disappears (I checked with OMSI Tools)

1. Which add-on or mod (map, vehicle, modification) do you have a problem with? Check whether there is already a freeware thread or a DLC thread about it.

>Grand Porto 2021

2. Please describe the problem in as much detail as possible. What happened or what might have led to the error?

>when I do the 304 to Santa Luzia after the stop "Alberto Sampaio" there is a hole in the map and I can't continue the route, I reinstalled the map, checked if I have everything for the map with OMSI Tools but the hole is still there. I don't know how to solve this because as I said I checked the map with OMSI tools and I have all the objects and splines

I reinstalled the map several times but the it doesn't helped

3. Please add a log file to your post, either in a spoiler, code block or as a file attachment.

4. If there is a helpful screenshot of the problem, you can upload and include it as a post attachment.

But I left and the logfile of the time of the incident is gone

How to fly?

When I load a random location (load without buses) and I click the left mouse button nothing happens, I can click the right button but it just makes me go further from where I spawned but the center will be the spawn location and with the mouse wheel I can just turn around

I added it as spoiler, I wasn't able to fly so i just spawned the default NL202 and just relocated it several time until I reached the place with the problem

I noticed that towards the end there is an error about a tile in lines 2160 and 2178 of the logfile but I don't know what it means

here it is

thank you, but how is it connected to the map and where I can find the missing files?

I installed it, it didn't help, I attached the new logfile, I noticed that there still an error about the same specific tile in lines 1230 and 1239 of the readme, it says that there is something wrong in line 23663 in the file of this tile but I don't know how to solve it

Line 23663 is the 0 at the bottom of the picture

It works! Thank you very much!
Maybe something went wrong when I installed the gcW pack in the first time
