Good afternoon, please check the work of Frustum. Since after version 112, the walls of the swamps on the map stopped showing me, I showed this in the video, and the second bug you successfully fixed, I wanted to show it at the base location, but everything worked fine. Thank you in advance.

I’ve checked the release notes of `r112` but nothing seems to be responsible for this glitch.

Any chances to demonstrate the problem with a live example ([https://jsfiddle.net/f2Lommf5/](https://jsfiddle.net/f2Lommf5/))?

This will make it easier to analyze/debug the issue.

It will take me some time for a live example, well I will let you know how I will make this example.
