Summary
If you build a platform, and then add walls of any type to it, and then later decide lets say you want a half-wall instead of a window - You can destroy the existing wall, but it will not let you replace it with a different wall type, only the same wall that existed there prior.
I can confirm this issue. It happend to me at least 3 times when I tried to deconstruct a wall and wanted to replace it with a wall with door. However, it does not happen every time. I don’t know when or why the issue happens and when it does not happen.
I found out, that as a workaround you can destroy the floor next to the wall and rebuild it. Then you can build any wall type you like.
This screenshot shows an example where I removed a wall part, but I was not able to build the wall with door:
Can you confirm if this is still happening for you in the latest update?
In my testing I can only recreate this issue if trying to build a half wall after deconstructing wall in the same spot.
Yes, the problem exists still in 0.80.00, Epic, PC. But you made the right observation, Night_Snake. As I said, the problem does not happen every time. And I think you found out why.
I made some tests with brick window walls and half wall, which were build in 0.76.01. I am now in version 0.80.00. If I deconstruct a brick wall with window, then I can build …
brick wall
brick wall with window
brick door frame
wood wall
wood wall with window
wood door frame
NO brick half wall
NO wood half wall
If I deconstruct a brick half wall, then I can build …
NO brick wall
NO brick wall with window
NO brick door frame
NO wood wall
NO wood wall with window
NO wood door frame
brick half wall
wood half wall
Then I made the same test with a completely new wood foundation which I build in 0.80.00. I have build a wall, a wall with window, a half wall and a door frame (all wood). Then I deconstructed all four.
At the place of the half wall I can only build a half wall.
At the place of the others I can build only all the others but not the half wall.
So I think it is clearly a “half wall no half wall” issue, in both directions.
