Warlocks can have 2 (or more) -wards simultaneously

[Raposa]

I have a warlock and have casted its Dark Invocation: Glyph of Forestallment once, rested (at the same area, without leaving), casted it again a few meters away from the previous ward and now there are two -wards.

I was unsure whether it was just a visual bug or not but common sense makes me believe the previous rune should disappear upon casting a new one, however I'd never taken this warlock feat before so I am not sure.

I have been told this is unexpected behavior and/or a bug, hence the post.

I couldn't replicate this in the PGCC.
Perchance, did you logout inbetween castings?

A fix for this should be live.
Locking and archiving.
