Can't log into character, possible companion bug?

Character I can't log in on is my lvl 71 amazon. Every time I try to log onto her I am greeted with this error screen:



I'm fairly certain this has to do with my companion that I gained from a map. It's an armoured beetle with the following 4 modifiers: Armoured, Cold Resistant, Energy Aura, Trail of Lightning (I think).

The game is trying to load me into a Decay map if that's important.

EDIT: After the instance timed out I was no longer getting that error message
