Typical mistakes, examples, that can lead to navmesh generation failure?

Hello!

I have a specific problem, i have encountered several times, but couldn't find the answer for.

In DaNetGames, specifically Enlisted, the sandbox editor's navmesh generation can fail on specific tiles. For example:

The tile that returned this error:

Has similar complexity regarding RI as others. Multifloor buildings, fences, etc. I see no reason why would navmesh gen fail in that tile. I cannot use DaEditor's navmesh generator, as i need to add assets inside sandbox and that needs navmesh to be rebuilt again.

My question would be:

• What can cause the above error? Could you tell examples, as what to look for? RI blocking hallways? Is it related to collision? Error log and in-game logger isn't very helpful at all.

EDIT: Modifying tile size can solve the problem but now i have holes in my navmesh. Still would like to hear opinion/answer on this.
