Okay, thank you for taking the time to look into it. I will provide more details if I find anything else.

I had repeated the same thing 5~6 times but experienced no crashes when the ramps were placed or constructed.
The engineers were once stuck around one of the completed Short Ramp IV. But I cannot claim it has something to do with the issue.
I would continue the same test a little more, this time on more bumped terrain. Please let me know if you notice something.

For now, my advice is that:
Before and after you build short ramps, save and reload the game to stabilize the NAVMESH and collision.

I tested the ramp issue. The steps are as follows;
→ Test Image
Built Wall IIIs and attached Short Ramp IIIs onto them.
Upgraded Wall III to Wall IV.
Removed all of the Short Ramp IIIs using both the right-click menu and the Dismantle button in the bottom left menu.
Entered the building menu and built Short Ramp IVs.

No problem, thank you for making the mod. Let me know if you need anything else.

@xchg
That is the info I want. They are the short ramps for regular wall IV.
Thank you for the quick reply; it helps the experiment to research the issue.

I am honestly not sure what the difference is. It was the level 4 ramp that let you select between left and right sides of the wall.

@xchg
Thank you for reporting. I will look into it.
Could you tell me which ramp caused the crash, if you remember?
Is it the ramp for the short wall IV or the long(regular) wall IV?

I had some level 3 ramps in their walls, I upgraded the walls to level 4, removed the ramps, and when placing *some* of the new level 4 ramps, my game crashes.

@DOG Thank you very much! :)

@MARH Corrected. Thank you !

I prefer a translation mod that requires its original mod, but you have my permission to translate the "Short Wall Ramp" mod.

Also, if you have time, could you include the note of caution about animal passage in your translation mod's description? My English description may not be enough for others.

Thank you for trying my mod. Happy holidays!

@MARH
Permission to translate your mod into a language I can understand? With links to the original mod and the author. Thank you!

need ah patch for Short Wall Ramp with Japanese Style Walls

@Datboi
Thank you for letting me know.
First, try the NAVMESH rebuild command, Shift+Ctrl+F11.
If it failed, please give me more details about the issue.
・What type of short ramps cause problems？
・Where the troubled ramp built? It would be helpful if screenshots were provided.

Generally, if a ramp is tilted, characters cannot climb it. And bumped terrain can block the ramp's narrow and steep pathway.
I guess those are the cause of trouble, but I need more information about it.
I am sorry for the inconvenience.

Hey I have a pathway issue with this mod. When I make my guys build stuff using these ramps to go up the walls they just get stuck and don't move so I have to select them and manually make them go up the stairs. They won't go up the ramps naturally, it's only sometimes. But most of the time they just get stuck at the steps

Thanks!

Thanks to this mod, I could build ramps in the lower level 3 walls I placed arround my base without destroying them and building them again.

@MARH
Thanks a lot for the answer)

@zubrjr
You can use "sideways wall ramp" and this mod together without problems.

Cool mod, thanks for your work, will it be compatible with "sideways wall ramp" or it is better use only yourse?

Nice scaffolding

굿!
