DRG Nextbots struggle to climb up on terrain geometry

[fiercestwarrior]

DRG Nextbots seem to struggle to climb up on cliff/ledges, it seems to work slightly better in singleplayer. I've attached a video (on a server + gamemode) as an example. I've also attached the relevant map and code (and models).
