Crash: Out of nav links. Need to increase maxLinksPerCell:17

This became reproducible on the attached save. 

Patching the NavGrid constructor to double max_links_per_cellmax appears to fix it (although probably far too heavy handily.)  If I understand the code correctly, I believe one of the following needs to be increased (since the error is reporting 17, and these are configured with 16 + 1):

GameNavGrids.CreateDeckoBabyNavigation

GameNavGrids.CreateDreckoNavigation

GameNavGrids.CreateFlyerNavigation

The Clone Dump Cycle 269.sav

Could you confirm that the error occurs when loading the save without mods? I loaded it without mods installed and didn't see the issue you describe. It may be that one of the mods you're using needs updating for this patch. As you say, if a mod increases the number of possible nav links due to pathfinding changes it will also need to bump the max_links_per_cell for that nav grid.

I am also getting a similar crash and am curious if you found a solution.  I have reinstalled the game but still get the same error before the first cycle completes on a new colony.  I run with a comical number of mods and have begun isolating variables, but it's slow going.  Is it possible to manually increase the maxLinksPerCell to something above 17?  If so, where is the file location? I'll report back here if I figure it out.  Here's my crash log...

I've had this problem just a couple of minutes ago and I fixed it by removing Pacu Pathfinding Bugfix mod. I don't really know why it works but it works.

Thank you so much!!!  Your fix has made my game playable again!

For me, it's needing to raise it to 33 and not 17, but same issue. Tried mod-less, still happens.

I have almost the same error now, any ideas how to fix this?

I found out it was a mod I installed. It is called "Slide Down Ladders" and the bug only appeared after over 400 cycles. Strange.
