So last night when pents were very very busy, and i was penting lt colns i decided to snag a couple of coln pents before going back to lt colns. A colonel gargoyle(i looked to verify rank) somehow successfully followed me back into lt colns. While killing it wasn't an issue, it shouldn't have been capable of following me into lt coln pents.

Unless a NOMONSTER barrier has been specifically set up the the gargs and grolms are unrestricted.

We did put a few barriers in a long time ago because players were leading NPCs out of the area to make faster solves or to lower ranked areas to create mischief.
We also added the change that if the garg/grolm was too far away from the source pent then it automatically died (in response to the leading away issue).

So I am not sure this would be technically classified as a bug.

However, if it is causing an issue we can add a barrier but there are many other areas that also do not have the barriers. (I do not recall how many we put in).

Added NOMONSTER barrier between Lt Col and Col pents.
