[469b] Bigger collision size on actor sometimes produce hit invisible walls

[SeriousBuggie]

Reproduce:

1. Start map MH-XV-GiranTown2021v1_dbg.zip (All assets for it you can find in full map: https://ut99.org/viewtopic.php?f=5&t=15020 )
2. After exit from start house, on left side exists way:
   
3. You can go here forward to left house and not see any invisible wall.
4. Now enter in console: set playerpawn collisionradius 135.

Expected result: You able walk here as before.
Actual result: You stuck into invisible wall.

If you use smaller values, like 40, invisible wall be smaller in width:

If you use bigger values like 200, invisible wall prevent walk you even on bright road far away from building:

Practical meaning of this issue:
Player able run where jeep or tank hit invisible wall.

Typical BSP cut obstacle

That map exists in various versions:

• Parent of all: MH-(dU)Giranbeta.unr (without monster, with brushes, without BSP error)
• Version of Red_Fist: MH-GiranTown.unr (with monster, with brushes, without BSP error)
• My fixed version of Red_Fist's version: MH-GiranTown+SBFix1.unr (with monster, with brushes, BSP error not tested)
• Thunderbolts version: MH-(dU)GiranTown(2021)V16.unr (with monster, without brushes, with BSP error)
• (unknown)'s version: MH-XV-GiranTown2021v2.unr (with monster, without brushes, with BSP error)

Sadly brushes were remove in map version in question, so a rebuild is not possible.
Also this is no answer to the question why smaller collision radii are not affected by the BSP cut. :-o

This looks less a problem of the game and more a problem of the map itself.

Game must be consistent. If there bad spot on map, there must be invisible wall for all size actors. And width must be same for any CollisionRadius.
