Node link 2 issues

Hi so my enemies are using the node link 2 in order to use a ladder one link at the bottom another at the top. The only problem is once they use the link if it isn’t exactly perfect the enemies base will be off and they will clip through the terrain for the remainder of their ai existence. Is there a setting I’m missing for when they use the node link it automatically assumes that the enemy is still grounded. Thanks for your help.
