Colision issue - mobs going through gates near bridges

[Mortisinmi 8]

Hello!

 

I have a bridge close my fences gates, gates are locked. When i pass the gates followed by spiders, spiders ignore the gates and pass them like there is nothing to stop them. Gates stay closed, there isn't the animation when humanoids pass a gate. It's like spiders are ghosts moving into walls. The gates and the bridge are not on deed. 

 

Before when the bridge was built, there were gates at the same place but i never seen any spiders going inside. They remain behind on the bridge, blocked by the gates. I didn't have the problem with others mobs, only spiders.

Same exact issue.  I've had a troll, hellhound, and brown bear all follow me through three locked portcullis.  All three portcullis were connected to a bridge.  This was on Wurm Unlimited, I cannot attest to Wurm Online.

Bridges allow mobs to bypass locked gates/doors.

 

Don't use a bridge near animal pen fences, and if your home has them, expect hell hounds and trolls to chase you clear inside.
