This problem only occurs when a new crater is made in the terrain. This can be done using rocket launchers, grenades or other explosive tools. I noticed this bug when I started working on testing my explosive weapons in studio in solo mode and in server mode.

This GIF shows me blowing up completely solid terrain and the third crater in has not rendered properly as I can see through to the other side except I cant walk through it obviously because there is still a wall of terrain there it’s just not rendered correctly.

As you can see from this next GIF, the more I blow up the non rendering terrain craters the bigger the invisible rendering hole gets.
This problem is not just happening in studio it also happens when I play the game as well. I have tested this on my computer as well as my Iphone and with graphic settings set to the max and the same rendering issues occur. Also the bigger the blast radius the bigger the invisible holes become.
I if this is a roblox problem which I think it is, then I hope they can fix it because it ruins my game.
Here is the repro file, just shoot into the side of the mountain until you see a big invisable hole
