UnrealEd-GPF when unaligning a broken surface

[Barbie]

In a map are a few "broken" surfaces, these ones are close to ASMDAmmo0:

When I select them and choose "Unalign", UnrealEd throws an GPF:

Sadly the mapper had removed all brushes.
---
EDIT: Map's name is zp01-umssakuracrashsite.unr and map is from package "SP-ProjectZephonV120".
EDIT2: Problem stays in map of package "ProjectZephon_BattleforFreedom_v2.0". Also brushes are removed in the map.
EDIT3: Added UnrealEd-Version:

Make github issue with attach broken map and specify reproduce steps.

Odd thing here, I couldn't get textures to go back to default, it was a huge terrain. It seemed like I made them scaled way high large, then worked my way down to 1, and then the textures looked right after trying to reset them, they just would not reset, can't remember if it crashed or not..

I only ever use ver 436.

Last time when I was about to solve some Textures, map was not saved doing some error and looping (it told me something about lazy array load blah blah) until I closed Editor forced (469c). As result I used 469b and later 436 for other tasks...

Buggie discovered that the "brokenness" is only shown with the software renderer. So the problem has only a small relevance.

I'm using D3D9 in every single Editor.

Obviously fixed in next UT patch, see Github: [469c] GPF in UnrealEd when unaligning a "broken" surface #1254
