Bad pathing with waterfill and landfill

[veden]

Hi, I am experiencing some issues with the biter pathing regarding waterfilled land landfilled areas.

The version of Rampant: 3.1.2
What is your map evolution ~ 57%
Was Rampant added at the start of a game: Yes
What mods are you using? MANY: SE, Some of bobs mods, RitnWaterfall, landfill for SE, landfill plus, nice fill, alien loot economy lite, big bother, factorissimo2, merging chest, loot chest UPS, quality of life research, RPG system, time tools, YARM, etc. (All of them are connected to the save)

A brief description of what you are experiencing:
I am having problems with the biter pathing, mainly due to using waterfill and landfill. They do not walk over unprotected landfilled areas. They "path" (run) into water-filled areas and congregate in certain spots, which causes massive UPS drops. (Screenshots 1 and 2)

They would rather path around the entire map than attack the nearest walls and turrets. (Screenshot 3 and video)

Here, is a video of the pathing behavior: https://youtu.be/wq1LjEYFC1s
